Mental garage
There was an interesting analogy that David Goggins described on a Joe Rogan podcast a little while back. He said that the mind is like a garage and most people just have a bunch of junk in there. If you don't organize it and put things into their proper place, then you can't get a car in there, or in other words, you can't focus on anything big and worthwhile.
Although he's coming at things from a different place as an ultra-marathon runner, it really seems to jive with a lot of thoughts that resonate with me from Cal Newport as he talks about eliminating distractions and focusing big, blocks of the day on productive, deep work.
From my experience, which is closer to that of Cal's than David's, I have done pretty well eliminating distractions, avoiding social media, etc. while also putting lots of valuable activities, like working out, on auto-pilot in the background. This leaves me lots of space to work on big things that actually move my business forward during the day. So, although I'm not having to overcome lots of pain and personal suffering to run ultra-long distances like David Goggins, I can get on board with his analogy about the mind. Get all of the small stuff in order, otherwise you won't be able to work on the big stuff that really matters.
