Simple advice from Seth Godin on building your reputation:
“A path on the way to building a reputation:
When someone asks you a question, they get an answer bigger than they ever expected.
When someone gives you a project, they get a plan scarier than they hoped for.
When you take on a project, you finish it.
If this is your reputation, what sort of projects and gigs will you find yourself getting? Not a good way to fit in, but an excellent way to be the one people seek out.”
