What did you mess up the last gig? What did you try to do in rehearsal that didn't work? What are you practicing that you are having trouble with? What do you need to know the next time you get with musicians?
That's what you work on.
It's nice to have big time goals, and you need them to keep on track, but having a clear focus on the next step and working on that is the key to long term improvement.
One of the big problems that face people who are on the way to getting it together is to make a goal that is, at the time, too big to reach. (Teen Town at a faster tempo that Jaco, Grooving better that Victor, etc) It gives you something to talk about and sound important, but you really need to hit those ii-V7 patterns in all keys, or learn the whole neck, or read a simple etude, whatever the next step is.
Organize your work. Be patient, it's a process, not an event.
