I'm never going to do anything with no reward attached
Are you for real? Why won't you do things without reward?
I don't want to work without being paid for it. I want to sit on the couch all day
While I can understand the impulse to want to be paid for your time, if you are just sitting on the couch all day you may as well help others. It is good to give to others who need help instead of only working when you are paid to do so.
I'm not going to do anything in my life with no benefit.
Sometimes that's not how the world works, like internships. A lot are unpaid but you gain a lot of experience! It will pay to be less selfish and do things for the benefit of others, maybe you'll like it!
