Sure. But in my experience, what works better is remembering happy times. Or rather, represencing happy states.

And once I'm being happy and optimistic, it's natural to persevere and accomplish stuff more effectively, and I have desired results. That is, "be -> do -> have". Which is just the opposite of the western cultural default of "have -> do -> be". As in: "If I were wealthy, I could do all this fun stuff, and then I'd be happy."
