Old sayings contain wisdom that has withstood the test of time. 

'Patience is a virtue.' That saying contains a simple, valuable piece of wisdom: you will fare better if you choose patience over impatience.

'Good things come to those who wait.' That saying contains the wisdom of 'patience is a virtue', however, it stretches that wisdom a little too far. 

Waiting - patience alone - does not cause good things to come. Good things come when we work the right way at the right things and understand that good things don't always happen quickly and sometimes good things take mysterious routes before they arrive. This is consistent with a high-level of (but not a zealous/fundamentalist) belief in the Law of Attraction...i.e., I mean - in broad terms, the good things we do will, some day/some way, bring good things to us.

Good things come to us when we work the right way at the right things. Perhaps, not all the time but at least some of the time. Unless you hold a fatalistic viewpoint, a belief in pre-set destiny, you believe your actions will generate results. And, you believe working the right way at the right things will tend to bring about good things.

Good things come to us when we combine patience with good work.
