In Japanese they have a term called Kakugo which according to my dictionary means a resolution or resolve. But I think the term Kakugo encompasses so much more. Kakugo is like a combination of self-belief and an intervention, but it can be for things that you haven't done before, and more for things you are going to do.

Kakugo can be hard to get. You have to truly believe in what you're about to do, and you have to believe that it's important. Sometimes it helps to have an actual intervention, but when you don't have that, you have to trick yourself into getting it, or having had it. Otherwise you're like a wandering wolf with nowhere to go.
