If I worked a long day I thought I was being productive, but was I?

According to the energy project, humans can only be productive at full capacity for 90 minutes before needing to rest and renew your energy. I thought I could trick my level of energy with caffeine but really I would probably just crash harder later.

Needless to say, after hearing this speech I’m going to try to run at maximum capacity for 90 minutes and rest and continue. This means if I don’t respond to your email right away I’m resting. I’ll get back to you when I’m ready for my next 90 minutes. Check out www.theenergyproject.com for more information.
