Enjoying what you do

I am beginning to see that I desire a workplace where I am challenged to do something great/significant for the life of an individual or many. Also the environment has to be positive and encouraging - people care about you and are friendly and good work is noticed and praise is a constant. I guess making a change in people's lives and doing something, no matter how small, that makes a difference for somebody, somewhere, is what excites me and makes my day. News editing . . .
