I was reading about somebody who was bemoaning the idea of chasing peak productivity in your life. I am a big fan of peak productivity in my life, but not an unbounded optimization to squeeze life until there is no juice remaining. The chase for peak productivity is really about optimizing the hours you spend working so that you can provide an amazing life for yourself and your family while not working 18hrs a day.
If you chase peak productivity for the 5-9 hours each day that you work and can deliver double what the “normal” worker can in that time, is that not an objectively good thing? You can nearly handle two jobs at once while investing little to no more hours than the person who does not manage their time and attention as well.
Search for peak productivity and discover optimized hours along the way. Don’t work more hours, push more work into your hours now.
