How about working out? I recently found out that the most productive engineer on my team runs every morning before work which makes a lot of sense. He's always firing on all cylinders.
I admit it feels great and it does help - but it doesn't really help me turn the tide when I'm in the 3+week phase of inability to focus on anything at all. It's also super-hard to do it in this phase.
But I will try again, thank you for reminding me it feels good.
