The best executive is the one who has sense enough to pick good men to do what he wants done, and self-restraint to keep from meddling with them while they do it. – Theodore Roosevelt
A leader is a leader not because he does everything himself, but a leader because he delegates the right jobs to the right people.
You can’t be in multiple places at the same time nor can you do multiple tasks all at the same time. But all these tasks need to be done and done on time as such delegation is key.
So you can agree that it is important to have people help you and not try and do everything yourself. But simply delegating tasks is just part of the idea. Having the necessary restraint to hold back and not interfere in their work is just as important.
So make it a point to be clear to yourself and steer far away from interfering with your team mates business. Once you delegate a task you have absolutely no business to help complete that task unless asked to. Remember that and you’ll be fine.
