I think the 80/20 rule can lighten this mood. The theory that you get 80% of the result from 20% of the effort. Kids are a unique responsibility... To some parents. But the rest of the stuff, you don't have to be perfect, but put some effort in. A bit of exercise, a reasonable diet, a job you don't hate that pays enough. What gets marketed is people living perfect lives, the reality is few people have the energy or discipline to squeeze every moment.
