I wish people would do a little bit of yak shaving when they run into errors (usually some form of merge conflict when pulling) to learn how to fix them, roll back, etc. They would learn how to appreciate the power and flexibility of git then.

I've helped people in my own open source project when they hit git roadblocks. They've never needed to save out their work and wipe their repo. There was always a solution within git and once they learned it, they really understood how version control worked much better.
