Have to prioritize. Yes it's painful. I'd love to do all of them, but only have time for about one at a time, so pick the one with the highest value to you and focus on it.

Take comfort in the knowledge that now that they are going online, they'll still be there when you're ready for the next one.

Me too, but I've signed up for most of them anyway. It's risk free and the only reward is personal: knowledge.

I signed up for almost all of them too. It's hard to choose which ones to fully dive into. I guess since they'll probably offer them again and again, I'll take one/two at a time.
