1. Write everything down.  ("[A]ll that can be thought can be written.")

 

2. Eliminate distractions. ("The one prudence in life is concentration; the one evil is dissipation."

 

3. Keep moving. ("There is no success in our art, but to take off your coat, grind paint, and work like a digger on the railroad, all day and every day.")
