zsh can mostly be thought of as a collection of enhancements to bash, so I find that rather than changing my thought process, I just try to use a zsh feature, realize it's not working, and do it the crummy bash way instead. If a feature exists in bash, the zsh syntax is usually identical.

Also just for the record zsh is installed by default on many OSes, including OSX, so you might be surprised to learn that some of your servers already have it.
