Become excellent at being reliably good before trying to be occasionally brilliant.

Occasional brilliance is unreliable by definition, and it is hard to build anything on top of it. Reliable competence is less exciting and it is what allows other people to plan, what gets you given real responsibility, and what accumulates over years. The brilliance, when it comes, then has something solid underneath it.

Aim first at doing your ordinary work well every single time. It is a less inspiring project than aiming for something remarkable. It is also the version that changes your circumstances, and it tends to produce the remarkable results anyway.
