If your project is important to you, don’t have someone else do it. There is no substitution for your work. It’ll never be as good as you want it to be because of how you have injected it with a soul.
However, surrendering control is a necessity in order to move onto new projects. There is going to be learning curve for the person that you surrender the project to. Failing to trust your team will cause you to stand still.
Move on or stand still. Make your choice. Just make sure the choice you are making is for the right reasons.
