I had a thought in the shower this moring that I do my best thinking there. I then thought about why I think best there and came to the conclusion that it was because I didn't have my phone to distract me.
It's too easy to grab my phone and fiddle with it to occupy my mind. I don't switch off and just let my mind wander. So to this end, I'm going to purge my phone of all consumption apps i.e. games, ebooks, news, mastodon for at least 4 weeks. I want to see if I find myself thinking more because I do enjoy having a good idea.
