Think I'll eventually get asked to participate in other groups?

I started playing with my first jazz group 5 months ago or so. I'm not as good as I like. My voicings are basic. I just started with Jazz Keyboard Harmoney by Phil degregg. On chapter 1 and I won't advance until I have it all memorized and can play everything effortlessly. Feels like it's going to take forever to get thru the book, but I want to have all these voicings at my disposal effortlessly. So I'll take as long as it takes.

Anyways. Everyone in my group plays in other groups. I figure eventually someone will ask me to play or sit in with another group, and I hope the timing of that happens when I have more voicing experience in me. There is also a Thursday night jamn a lot of them seem to go to. I don't want to go until I get these voicings down.
