Much like a zen master, G.K. Chesterton reminds me where to turn for mentors:

Distribute to dignified people and the capable people and the highly businesslike people among all the situations which their ambition or their innate corruption may demand, but keep close to your heart, keep deep in your inner councils the absurd people; let the clever people pretend to govern you, let the unimpeachable people pretend to advise you, but lets the fools alone influence you; let the laughable peope whose faults you see and understand be the only people who are really inside your life, who really come near you or accompany you on your lonely march towards the last impossibility.
