I second Eliot's point, a leader's job is not to be the person with the best skills, it's to have a clear understanding of the bigger picture and help everyone understand it too, stay on track and make a success of the project.

I asked my ex-employer in what ways I could improve and got a similar point: 'your technical skills are great, stop worrying about that, but if you ever want to be in a lead position, you need to work on your people skills'
