I made my own bandwagon to ride on. I'm not really a leader type person either but it hasn't been too bad. At least I get to decide what kind of group it's going to be when I'm heading it.

I even fell off the bandwagon once, tried someone else's, didn't like it and made one again.

All I can say is, if you have the motivation, you will reach your goals eventually. I've seen people in endgame that joined far later than 2 months into ARR.
