It's worth it, just have to get through that first few days where you want to run back to familiar territory. I don't know of any shortcuts, just repetition. My particular choice is Vim, and my only advice would be don't try to master it all at once. Work on just editing text, saving and opening files, find/replace. When that's all second nature, get wild and start using window splits, macros, and remapping keys(if you want to).
Once you're all trained up though, I think you'll really be happy you spent the time.
