"There's a time for every purpose under heaven" comes from the famous words in Ecclesiastes 3:1-15. Timeless wisdom right there (pun not intended) Timing is an art that is hardest to master and there's nothing better than doing the right thing at the right time. It takes a lot of wisdom to discern the times and seasons but it is always best when you get it right. For example how beautiful it is say in a game of football when the striker arrives just at the right moment to receive the pass and strike the ball into the back of the net.
That sense comes with practice and attention. Learn it!
