What percentage of the things you do are because you want to? The rest are because you have to.

This is why having work, experiences, relationships, etc.  that you're able to enjoy is so important. And why having passions, relationships, purpose, hobbies, etc. into retirement is important. 

I became used to doing things I did not want to do or I'd get a spankin'. Chores galore dawn till dusk growing up on the old farm.

I think only about 10% of things were for pleasure, going fishing, skating, etc.

All different now in retirement, there is not much that I have to do. And there are significant alternatives to boredom.

90% of what I do is because I want to.  I've reached the age where I don't have to do things because someone else wants me to.

I only do what I want to do these days.  Paying bills is not fun but I don't mind doing it.  It supports the economy and jobs, and get my the services I want.

100%. I do nothing that doesn't have a payoff for me.
