It's a choice between pleasure and accomplishment I guess.
Spending time with ones family IS an accomplishment. Climbing a hill IS an accomplishment. Both pleasurable activities, to my mind.
The choice is between which accomplishments give you pleasure, not between accomplishments and pleasure.
You don't have a family? Ok, spend all your time imagining nice stuff and give press releases about your imaginary stuff, but don't call it job, call it hobby. Are you still calling it a job? Then you shouldn't be spending so much time on it.
