In his post on Zanshin, a state of relaxed alertness, James Clear writes:
Great archery masters often teach that “everything is aiming.” Where you place your feet, how you hold the bow, the way you breathe during the release of the arrow—it all determines the end result.
I like the idea of zanshin, but I like more the insight that everything is aiming. How every piece of your attitude, preparation, body and state go towards influencing how you perform. No detail too small. Tennis coaches, for example, reinforce being in the ready position before a ball even comes your way. Experience teaches you it does matter.
The concept reminds me of one of my favourite quotes which I think pretty much sums up a great approach to life as a whole and also how I view luck:
I will study and get ready, and perhaps my chance will come.
