I agree with all of the above, but stopping with "don't" is not very helpful---people do do things that they are told not to anyway, and it makes a whole lot of difference if they know how to recover from the fallout of their actions. It would help to teach "reset --hard" or something that lets the user to return to a known state. It may not necessarily be the state the user would want to go, but it is still better to be in a known stable state and be able to complain "I lost my stashed changes" or "I lost a few commits" than to be in a state where the user is totally lost and do not know what to do next. Of course, that kind of coaching is not something we should do in our error or advise messages, but in an early part of the tutorial or somewhere, perhaps? Thanks.
