Fill your bowl to the brim
and it will spill.
Keep sharpening your knife
and it will blunt.
Chase after money and security
and your heart will never unclench.
Care about people's approval
and you will be their prisoner.
Do your work, then step back. The only path to serenity.
Verse 9. Tao Te Ching Stephen Mitchell translation. I also like the Daily-Tao website found HERE
