The most critical element of delegation isn’t trust. It’s patience.
Absolutely nothing can be delegated in less time than it would take you to do it, if you’re handing it off for the first time. The process of giving away work is work! The whole “if you want something done right, you have to do it yourself” mentality is just a side-effect of being impatient.
Don’t delegate because you’re busy. Delegate because you want to grow.
