"If anything is worth doing, do it with all your heart."

~ Buddha, 6th century bce Indian mystic and founder of Buddhism from The Dhammapada

That makes it pretty simple.

If it’s worth doing (very important distinction) do it with all your heart (equally important distinction).

Decide what’s worth doing. (Seriously. Are you doin stuff that you shouldn’t even be doing? B/c that’s the stuff you tend to do half-ass. Best solution? Stop doing it—either immediately or make a plan to stop doing it…)

Once you’ve decided to do it, give all your heart to it.

(Pretty, please.)
