fall in love.

with something other than your work.  single minded focus in great for a time.  but your brain needs a break.

have or find something else to be passionate about.  find a regular activity to distract you.

workout early…work out late.

walk your dog…walk the neighbors dog.

garden/plant/week/mow the grass.

whatever it is.  love it.  nurture it.  look forward to it.  your work will thank you.
