Play piano.
Don't get me wrong--it is not something I do well or even competently---on my best days, I barely qualify as 'advanced beginner.'
It requires my complete focus; I use my mind and my body.
Best of all, the 'chatter' stops.
It is useful for my work too. Reflecting, I came up with 3 things.
1. Some skills are very difficult to learn and these are not the same skills for every person.
2. It is ok to demonstrate/practice new skills even at a level of incomplete mastery. (i.e. Everything does not have to be perfect)
3. Satisfaction or enjoyment is not dependent on a high level of skill.
Pulling weeds is good too.
Each day is a gift, that's why it is called the present.
