I’m married and have kids so there’s always something going on in my life and I don’t get many opportunities for “peace and quiet”.

What works wonders for me is swimming. I only do front crawl so I’m basically staring at the bottom of the pool for the entire duration of the swim. It’s incredibly boring. But something happens in my head, I can just think better. I will often take a problem from work and mull it over in the water, and very often I come up with either a solution or otherwise put it in perspective or some other strategy to deal with it.

Highly recommend. Also at my age (mid-40s), some form of movement that is gentle on the joints is appreciated.
