A lot of philosophy and "wisdom" is in telling people what they should do and probably already try to do without giving them the tools to do it.

A wise person realizes it is silly to tell someone "Don't hope that events will turn out the way you want" without giving them real tools to address their feelings.

that's fair, although i will say that people tend to complicate these things to a ridiculous degree, coming up with a laundry list of reasons they can or cannot make strides towards these goals.

The stoics developed tools you are asking for. You can find a good summary of them in the book A Guide to the Good Life: The Ancient Art of Stoic Joy.
