It's human nature to wait until everything is in place and life is perfect to--only then--get started.
But the magic happens when we are not ready. Actually, the further we are from 'ready,' the better. And since all is not in place and life is perfectly imperfect, we are free to fall (and get back up), fail (and win), and make lots of mistakes (and learn tremendously). We get to think creatively and figure out things along the way.
Meanwhile, we grow stronger, wiser, smarter, and more resilient.
Strive to be ready, but never attain readiness. Just start, and grow.
