I believe we are responsible for all that is good and bad in our lives. Sure sometimes we have unexpected good and bad things happen to us but it is ultimately what we do with it after the fact that determines our future states.
I believe good/evil right/wrong are points of view. I believe we all do what we have to do thrive and survive and if you judge others for it, then you judge yourself as well because all of us have done things in our past we are not particularly proud of.
I believe that ambition is good but greed is bad. There is nothing wrong with wanting more and even wanting to be on top. I don't believe it should be done by hurting others or taking away from people or taking advantage of people who are disdvantaged or vulnerable or through dishonesty. I believe in sharing the wealth (within reason).
I believe that having core beliefs set around loyalty, respect and honour will guide one through life to the destination they need to be. I believe in doing the right thing, even if it is not the commonly shared viewpoint. I learned not to follow the crowd just because, only if it is something i feel is the right thing to do.
I believe I can conquer any challenge and in my own abilities while knowing my limitations. I believe that while I am not perfect, I'm still pretty awesome and I wouldn't want to be anybody else. I believe I should be accepted for who I am and should not be forced to change, nor should I try to change people.
Most of all, I believe in me.

I believe these things based upon my life's experience.
