Grow up? ... Life is not meant to be 100% happy. Lots of things require work. If you live in a house it will rot if you don't fix it constantly. Your yard will over grow with weeds, tree roots will crack your foundation.

No one owes you a life. They don't owe you food, shelter, electricity, internet, etc. If you want those things you need to do something they want in return or do them all yourself (plant crops, hunt, setup a windmill or waterwheel, ...)

All that said, of course you should try to find work you like. It's better than work you don't. I've known people who like solving technical problems and are fairly happy at nearly any tech job. I've known people that like working as a chef because they feel good making good food for people. I've known people that like working as bartenders because they get to socialize every day. I've know people that like running an ice cream store because every person they hand the ice cream too gives them a smile.
