For what it’s worth, you’re not alone. I’ve been worrying over some of the same issues (limited time, aging monkey mind, etc). Ten-years-ago me laughs mercilessly at the modest daily goals that present-day me is setting to get myself back into better habits: read two chapters? write a page?
Now if you’ll excuse me, I need to go spend the day doing what ten-years-ago me swears I could get done before breakfast. 🙂
