Good post. I haven't set timers, but I've been trying to be aware of when I start to hit my limit. I did about 11 hours of work today - a whole ton of stuff - and then I started flagging towards the end of the day, but I had some more stuff I need to do. So I had a coffee, went for a 20 minute pretty intense swim, and I came back and was ready to go. Did more good stuff. This has been good for me - the challenge is just self awareness of when things are slowing down and then I'll do something like pack up and go to a cafe, go exercise, come back from the cafe, etc. I've gotten big gains out of shifting gears once slowdown hits, but maybe proactively scheduling a shift would work better - I'll give it a try.
