Via the Red Lemon Club, I came across this motivating post on 7 Simple Acts of Daily Self-Discipline that Will Make You a Better Artist written by founder, Alex Mathers.
I especially like his point on Clarity Thinking. Alex says, "One of the healthiest and most refreshing things you can do for the benefit of your creativity, productivity and personal well-being is consistent thought reduction. This does not mean actively stopping your thinking, rather, bringing awareness back to exactly what you are doing in the present, whenever you notice it straying off."
Check out the rest of Alex's post - and then poke around his site for more inspiration.
