so many kind IDs/persons and so many are ambitious in career. I met with one guy who seems enjoying what he is now and just everyday wasting his time, even I think he is more talented than I am. The difference is that I try hard to get better in career but he is just maintain his current living level. I don't know which one is better. Obviously, my life is full of stress, but his is full of relaxing, that's one obvious difference.
