a motto someone shared with me many years ago, “ki-lined”:
prepare for the toughest outcome.
expect little, if you must expect anything at all.
hope for the best. and more: hope for everything.
if you prepare for “the worst that can happen”, and you can see that you will still make it through, you can relax.
if you expect little, if you are not attached to the outcome at all, you can relax a bit more.
if you can hope for everything, you can step into each day with a chance of joy, and contentment.
