You'd also better show up.
Treat what comes next like a sales job, because that's exactly what you're doing. If you don't think you can sell, learn how. Sell your spouse on what to eat for dinner tonight, sell your co-worker on why they should bike to work, sell your mailman on a pair of shoes you're wearing. You won't get the job you want without first learning how to sell.
You'd also better know how to write. If you can write well, you improve your chances of selling better. Because writing is a form of selling. Be persuasive with your writing.
Show up again and keep bringing the enthusiasm.
Deliver more value than expected.
Grab their attention by making a promise.
Build a reputation by keeping it.
