Good luck is another name for tenacity of purpose.

Persistence changes the odds by increasing the number of times you are standing where luck could find you. Someone who keeps going gets more attempts, more chance of a useful accident, and more time for conditions to turn. None of that means the unlucky simply did not try hard enough, because plenty of tenacious people get nothing back, and pretending otherwise is cruel.

What is in your hands is the number of attempts. If something matters, arrange your life so you can keep making them for longer than seems reasonable.
