The first time you try something, you’ll feel like you’re out of your depth, like you don’t know what you’re doing.
But if you persist, if you do it for the second, third, and fourth time, you might start to feel like you’re getting the hang of it.
A hundredth time, you’ll see clear progress, you’ll know that you’re improving, you’ll start picking up nuances and subtleties of the craft, and you’ll understand exactly how to improve even more.
The trick, of course, is to stick with it (whatever “it” is) for the first hundred times when it won’t feel like much.
Try to keep in mind that you’ll get better at it. And if it matters (and you probably wouldn’t be doing it if it wouldn’t matter), it is definitively worth the effort.
