Simply put, ethics are the codes that guide our  thoughts and actions;  they determine the purpose of our life. This seems  to be an easily  understandable concept, and really, it should be. Why  then, does it  seem to be so often neglected? The trouble, I think, stems  from the  education we receive at early ages. For example, we're taught  honesty  is a virtue. Great, but when the only answer I can get out of my  peers  about why we should be honest is: "Because lying is bad," we have  our  problem. People focus so much on secondary causes (virtue) that  they  are unable to answer or forget about the fundamental issues  determining  virtue, values. A proper system of ethics cannot exist  without first  defining values that determine such a moral system.  Virtue presupposes  value, because the purpose of virtue is to keep and achieve what we  value.
Values: (Objective) Reason, Self Esteem, Purpose
Virtues: Rationality, Pride, Productivity, Integrity, Honesty, Independence, Justice.
Before I give examples and definitions of these principles, I need to first explain the importance of objective   values. By objective, I mean based on facts. Our core values are   absolute and uncompromisable. They are not whimsical, and are by no   means utilitarian, in which concepts such as good and evil are   subjective from day to day. In the simplest sense, A is A, never B, just   as B is B, never A. This may seem extreme, but let me illustrate an   example. How many people do you know, from politicians, to coworkers, to   friends, that claim to like honesty, integrity, and justice? The   majority of them. How many do you know that truly adhere to the virtues   they want to live by? The number is probably much smaller. The reason   for this is avoidance, conscious or unconscious. People try to live by   virtue without ever bothering to understand the value systems that   determine it. The results can be seen all over the world today:   Religious radicals who claim that killing is evil, yet are willing to   take a life on a whim should someone disagree with them. Politicians who   preach family value, yet cheat on their spouses. Rioters who demand   "equality" from the government, but are willing to violate the rights of   others by burning private property. These are all extreme, but the   results of non-objective values are ultimately all the same:   irrationality and hypocrisy. 
Reason: Living within the  context of reality, ie, dealing with  facts. Individuals often spend too  much time debating decisions on what  "could, would, or should, be." They  make a tragic mistake by focusing  on ideas that are disconnected from  reality. As humans, reason is our  means to survival. We have few other  advantageous abilities.
Corresponding virtue, Rationality:
Rationality is achieved by living in accordance with honesty, justice, independence, and integrity.
Honesty: We  are consistent with the facts of reality. People  fail  when they disconnect themselves from reality. Lying is ultimately   self-destructive, because it forces one to be in constant conflict with   reality in order to maintain the untruth. 
Integrity: We  will always act consistently with our principles,  because our  principles were determined through objective logic. Short  term benefits  are considered, but they are never able to justify acting  inconsistently  with our principles, because ultimately that will be a   long-term detriment. We will not compromise our values under any   circumstances.
Justice: We will not exchange a higher  value for a lower one. We  reward individuals based on their  contributions to accomplishing our  goals and their adherence to our  values. Those who contribute the most  will earn the most. Essentially we  are a meritocracy in the purest  sense, and our creed is "Judge and  prepare to be judged yourself."  (with reason)
Independence: The  essence of this entire system of value and  virtue is individualism. We  push ourselves and others to achieve their  maximum potential through  individual thought and effort. Creativity is  only possible for the  individual. Teamwork is important, but only  through voluntary agreement  that acknowledges that our minds are  separate. The collective mob is  never the standard for value.  Individuals are responsible for their own  thoughts and actions, and  will be evaluated accordingly. 
Self- Esteem: A  strong work ethic, self motivation, and an  expectation to succeed. As  you can see, this last part, confidence,  could be easily misconstrued if  we didn't first value Reason. While we  have self esteem, we recognize  areas in which we must improve. One  should have strong personal goals  and place their long term self  interest on the highest pedestal.
Corresponding virtue, Pride:  Pride was once said to be the  highest of all virtues, because it  presupposed all the rest. One can  only truly be proud if they adhere to  all of their values,  objectively.  Pride comes from living honestly,  independently, etc.  Reason again, is key to this virtue, as pride can  easily turn into  arrogance if once doesn't maintain rationality. 
Purpose: I once read a quote by Albert Camus that said:
"There is but one truly serious  philosophical  problem, and that is suicide. Judging whether life is or  is not worth  living amounts to answering the fundamental question of  philosophy."
The most important question one can answer is: "Why live?" It seems so  simple but it's so often neglected. Ask yourself, what are you living  for? Yourself? Others? Can you truly ever live for others? I've found  the purpose of my life is the experience of living in whichever way I  rationally see fit.
Corresponding virtue, Productivity: 
Once we know purpose, we can commit ourselves to taking the necessarily actions to produce happiness.
The Six L's to Living:
Live Consciously:  One remains ever-aware of the present moment.  One of my favorite  writers, Seneca, once wrote that one should remember  the past, live in the present, and anticipate the future.
Live Purposefully: One seeks to reach ones highest potential. "No Goals, no Glory!"
Live with Integrity:  One knows and understands his/her  principles and lives by them  consciously and consistently. "He sets his  feet on a rock, not upon  sinking sand." - Godly Man, one of my  favorite songs.
Live with Self-Acceptance: One lives accepting who they are at the present moment, but acknowledges there are still things they desire to become. 
Live with Self-Assertiveness: One must honor himself and his values with word and action.
Live with Self-Responsibility:  One is responsible for their own  destiny. Some events may be out of  ones control, but in the grand  spectrum of life, the individual must  create the world they wish to  live in. This comes from my favorite  quote. "Do not let your fire go  out, spark by irreplaceable spark in the   hopeless swamps of the  not-quite, the not-yet, and the not-at-all. Do not  let the hero in your  soul perish in lonely frustration for the life you  deserved and have  never been able to reach. The world you desire can be  won. It exists..  it is real.. it is possible.. it's yours." - Ayn Rand
