If one wants to grow as a leader, one must learn to let go. Let go of the desire to be in control of everything. It’s much like letting your teenager learn to drive, even when all indications are that you shouldn’t ever let them drive.
When it is time to grow, good leaders let go. They ease others into roles they themselves were playing earlier, and move on. They are not insecure and so don't linger on in the previous role. They nurture, but don’t judge. They guide, but don’t micro manage. They encourage and don't damage self esteem. Good leaders allow others to explore their own space and help them become their own best versions. They don’t desire to create clones of themselves.
So let go of what is not yours anymore, and get on with what is actually yours now.
