Learn your weaknesses, learn to delegate and to trust others.
Once, I have worked with an "architect team". They were brillant, talentuous, very creative. One of them has lead the development of a software component. He has been in charge of a small team of developpers for this component. As he was very creative, he has "improved" the architecture many times during development. At the beginning, he was loved for his ideas, but at the end, the developper team hated him. Later, he was tasked to change the organisation of the source directories (and makefiles) to adapt to in house software management tooling. I have been asked to replace this guy because the team did not want to see him anymore. I have followed his ideas with as few changes as possible. It was a success. I think a good architect must be creative, but a good project leader must also be able to keep direction (limit changes). The creative guy should initiate projects, build prototypes, show roadmap, them find an accountant to replace him (someone who monitors planning, risks and costs). Either you are able to change your mindset according to project phases, or you learn to delegate.
