day no. 15,388: luck comes when you are ready

"It is better to be lucky. But I would rather be exact. Then when luck comes you are ready." 
-- Ernest Hemingway, The Old Man and the Sea

You can do everything precisely right and still not have things work out. You can do nothing right and things can end up working out somehow. But of the two, it is better to be prepared, for then when things begin to work out, you are positioned well to take full advantage of the fortune you find at that time.

Proverbs 16:9

A man's heart deviseth his way:

but the LORD directeth his steps.
