I am happy to say that I know I am a human animal, I know my humanity and I acknowledge my animal side. I have a life or death mentality and I believe in the thrill of the ride, life can be steered and you are the helmsman of your own vessel.
What others think of me doesn't matter, I will listen to opinions and may learn from them but the choice of wether to believe others or not is ultimately mine. I have done so much and been so many places , the things I have seen have given me perspective on myself and make me realise I am what I am. I like me.
We all have the capability to do great good but at the same time we all have capacity for great evil , it's said that man was created in Gods image ,,,I don't believe this but I do believe man created God in his image because we are the true creators and destroyers.
You are never what others percieve you to be, but you are what you think you are, belief in yourself is a very important quality and lack of it is a great drawback.
I have always found that it doesn't matter if I succeed or fail , all that matters is that I can say I did my best , we all have talents and finding our true talent makes a big difference to how we see ourselves.

Acceptance of yourself and your good and bad points is the most important thing (IMO) once you take an honest look at yourself and recognise your strengths and weaknesses you can then improve on what you wish to and that is the first step to being happy with yourself.
