I silence email when I need to get something done too Ted!
Fresh air is great advice as well (water helps concentration levels too).
Something I personally find very helpful is music - if I am coding I actually need it, and I usually have something like bassdrive.com on. For some reason, songs are a bit distracting and I seem to prefer mixes, particularly the higher BPM stuff, but it depends on the songs. Drum and Bass is definitely my go-to while working tho!
I also like a clean desk! If my desk is cluttered it just affects how I work - I have no idea why
I also agree with what he said in the video I posted in the first post, removing distractions is great - I often delete TikTok because it is just so addictive!! If it’s not on my phone I can’t open it This literally had my LOL’ing at 2am the other night
Aside from that, I think eating a clean diet can help too. Gluten is a known neurotransmitter blocker for instance, and I’ve definitely noticed a difference with it in or out of my diet.
