I've gone through the same thought (and emotional) process. I guess if you're enjoying it and it brings you happiness, that is the best reason to do it.

We have some advantages that only accrue with age. It seems you have a nest egg that lets you do what you want to do, that's a major thing. Also, you have a professional, social and experiential foundation that serves you in good stead.

I'm happy for your enjoyment. Best of luck!
