Everyone has to have a reason to get out of bed in the morning, and it's a jolly good thing if that reason is to do something one enjoys doing.
If it's something that not only one enjoys, but is also something that other people are prepared to pay one to do, then so much the better in my view.
I expect I will retire at some point, but all the time I can do something I love and get paid for it, I can't see a reason to.
