This is a wonderful question. I have a lot of classroom education (not in bookkeeping, or QBO), but the real thing all that education taught me is that learning opportunities are everywhere. I think each person has to find the learning process that works best for them. 

I am doing something so totally different than my formal education. For self-education, I have tried to find classes and workshops when available. I have read books. I have scoured the web. I have also networked, with real life colleagues and with virtual colleagues.

Lately I have been participating in a lot of online training. It's easily accessbile and usually high quality. I've also been trying to develop a larger network.
