Stay teachable. By that, I mean don't ever forget that you know very little and have a lot to learn. Don't become the '100 jump wonder' who knows everything.
Continue to learn. I've heard it said that some skydivers have 500 jumps, others have done the same jump 500 times.
Keep showing up. Even if the weather is 'iffy', show up anyway. There's a lot that can be learned on weather holds, just sitting around and talking. Listen more than you talk.
At this point, there's very little you can do to impress them with your skills. But you can show a good attitude.
