"I can write better than anybody who can write faster, and I can write faster than anybody who can write better."

Leading to a generalized strategy for success:
1) Identify two orthogonal metrics by which your work will be judged by relevant stakeholders.
2) Work / practice until you are better than anyone by at least one of those metrics (in practice, better than the large majority of your competitors).
The degenerate case involves being the best in the world by at least one of the metrics; more achievable is to be somewhere in the middle for each. To use our own patio11 as an example: be better at coding than anyone who is better at SEO, and be better at SEO than anyone who is a better coder.
