Cogito ergo sum" is Latin for "I think, therefore I am"
Everyone all have their own philosophy of life
In my life, I like to do the things what I want to do basic on without hurting others and others' benifits, basic on not breaking the nature and the law.
Whatever if it would be a fault for me, but if I know I should do it now, I will do it anyway.
People like to make up principles, but I don't like to be restricted by that.
So what things are right and have importance for me?
I can give example such as I am a person who has the sence of justice, I can't bear if something is unfair for me or others else, then I will do my hard to deal with and solve the problem, and make the things become prefect.
