Is it wrong to feel like I’m getting purpose from work?

I don't have an issue with working I guess but I feel miserable trying to keep up with the demands of bigger people than me, my body hurts. The only thing I really wanna do is live off grid and grow my own crops and just be free from the artificial construct that we've trapped ourselves into. Agree or disagree I just don't want to be stuck working like my life depends on it until I'm 80. Anyone else share the same thoughts or similar
