This question itself shows a little bit of privilege.
What keeps me going is having to pay the bills. And even after you pay bills you have to worry about retirement, and if you have enough for that you can worry about your family and friends.
Don't get me wrong I actually REALLY like my job right now but I didn't always like what I was doing. And probably one day I will also dislike what I am doing, but in the end you have to keep working so long as you need money.
