Try.

Assume, for a moment, that you're right about your ability. You aren't going to get better by not trying. You get better by practicing the skill, be it writing, weaving, or wargaming.

And if you're selling yourself short, you have even more reason to try, because not trying will stop you from proving yourself wrong.
