Is it worth to be good?

At first, with this post I don't want to recommand anyone to be a bad person. Not at all. It's just recently I have this thoughts if it is good to be always nice, careing, helpful simply althruistic person. Does it pay off?

I really don't like this approach to think about life in the bussines terms. I really didn't want to be nice for people because it will pay off. I wanted to be like this because I believed it is a right bahaviour.

Unfortunately life shows me that I have to be carefull with the althruism. That if I will not fight for something it will not really happen, and if I show people that I am a good person, they will simply use me.

Till not it is kind of right. I was working a lot as a volunteer developing projects. Yes I can say that I gained a bit of experience and fun time bla bla bla. But as a normal person I compare myself to others. They got much more, because of this bussiness rules, because of negotations and deals.

After so many years of my work in differen fields I feel used. I feel that I was giving a lot to the others - my experience, ideas, recommendations, partners, consultations, my time, my energy, my resources, my knowledge. The alternative cost was very high because it was my whole life as a student and all that time. And I see it now it didn't pay off.

It makes me sad when I see people, whom I teach, whom I helped a lot doin right now their own great stuff. I am praud and happy that I was able to help, but it makes me sad that thhey moved forward and I didn't, and I don't have a perspective.

Maybe I am overreacting. Maybe my life would be much worse if I would have been differnet. Maybe I shouldn't complain and see the positive sides (yes there are still many of them).

But is it really possible to be a good person, and not be used because of that, acheive someone, or even the good person must strat playing this trading game...
