If we are talking about success, I think it is important to consider for whom you want to look successful.

If you are in the wrong environment success might be meassured by your salary, your job title, the car you are driving or other silly things like that.

For me success is only meassured by my own standards, namely: am I working on things that I like working on? Am I able to do them the way I want? Am I making the world a better place by doing so? Am I getting better at what I am doing?
