The land will not produce a harvest if it never lies fallow. 

Rhythms of work and rest, productivity and refreshment, ebb and flow, produce the best results.

TRY THIS:

Know when you work best. Whenever possible, work according to your peak times of energy, creativity, and mental focus — and rest or relax during the times when those lag. 

Working with those patterns allows you to accomplish more in less time with less effort.
