We have seen what we have is an effect of what we do. We’ve seen what we do is an effect of what we are. If we are supposed to work on what we are; then what are we?
Each of us is a set of principles. However, since we are all unique, we can say that each of us is a unique set of principles. I call this a moral code. We are supposed to work on our moral code.
What is your moral code? It is the prioritization of your principles and shows through in your actions. How can you determine the order of priority? When you are faced with a situation and you have more than one option, the action you choose is a result of the principle that has a higher priority on your moral code.
For example, would you rather help a friend or go drinking? (In movies, usually when a character is introduced they will show the character making a choice. This is done to quickly show you the moral code of the character.)
Everyone has a unique moral code that is a result of their DNA and experiences. I call this the “original” moral code or “actual” moral code because it is the code the individual actually uses. Considering the number of principles and the permutations of their prioritization; the individual’s “original” moral code is more unique than fingerprints. If there are 150 principles (money, friends, animals, comfort, growth...), there is 5.7 x 10 to the 262nd power combinations. (That's a 5 with 262 zeroes after it!) Clearly this is more unique than a fingerprint.
Because the moral code determines what you do, the moral code is who you are. Also, the moral code eventually results in what you have. Therefore, the moral code can be profitable or unprofitable to the individual. In fact, there must exist a unique moral code for each person that leads the individual to maximum profitability.
For now, let’s call the most profitable one the “sound moral code” and the less profitable one the individual naturally has the “original moral code”. The difference between the individual's original moral code and his sound moral code varies for everyone. Some are born with less of a difference than others (e.g., Jesus? Mohammed?). The maturing process is really the process of modifying one’s original moral code into his unique sound moral code through reprioritization.
Your focus in this world is to convert your original (or actual) moral code over to the one that is most profitable for you. This is harder to do than it seems because society tries to convince you that we all have the same sound moral code. (Isn't that the point of some commercials?)
Ultimately this is done to control you. Groups of people can't be controlled until their uniqueness is denied. This occurs with organized religions that try to control people by saying they should all have the same "right" moral code. Society tries to control people by saying they should have the same "practical" moral code. (e.g., sex, wealth, toys...)
Converting your original moral code to your sound moral code is an act of creation.
This is going to require thinking. In fact, one could say, “thinking is man's only moral responsibility” because it is the cause of everything else for the individual.
Your ability to live is dependent on your ability to think (create knowledge). Ultimately, morality is choosing to think in order to understand this existence. Conversely, choosing not to think is death. This is done in many fashions: silence, saying "regardless of the facts (even if it is true) I'm still not going to believe it", focusing on discrediting or belittling, ignoring information, faking reality, lying, etc.
So the first step is to choose to think.
