Is being a pediatric OT or a Acute Hospital OT a rewarding career?

Hey everyone, so I'm a 27 year old male interested in a career in occupational therapy. I'm an extreme idealist and have a B.A. in environmental studies and a minor in GIS. I went into it with the idea of helping to change the world, save the environment etc... But the reality turned out to be different and I found the work very unrewarding. I'm the type of person who needs his career/job to be rewarding or else I will be extremely unhappy. I've also realized that I like working with people not at a computer. Lately I've become interested in either occupational therapy or nursing and have started taking the pre-requisites. I've done some shadowing of OT in nursing home settings and realized that is somewhere I could never work, but I've also gotten a lot of bad feedback from current RN's about the profession. I know every job has its bad things and there is never going to be something 100 percent perfect but I'm getting older every day so I want to make sure my next move is the right one. For those of you who work in either a Hospital setting or with children as OTs, do you feel your job is rewarding? I'm not talking about loving it every day but do you at least get some satisfaction when you come home from work and feel like your effort that day made the world a better place. I'm honestly not interested in making a ton of money, but I know you need a decent salary to enjoy life and hopefully have a family. Thanks for reading and appreciate any answers!
