No great thing is created suddenly, any more than a bunch of grapes or a fig. If you tell me that you desire a fig, I answer you that there must be time. Let it first blossom, then bear fruit, then ripen.
Epictetus
(c. 50 - 120)

I believe this applies to anything in life, all good things take time to grow. Just imagine how sweet life tastes and how hungry we are when the fig is ready to be devoured.
That's the beauty and wisdom of life; it is so simple yet so very complicated. I like simplicity so I often look for simplicity in things that sound complicated. So it is with this quote.
