Our actions lead our emotions

In one of the books I read - which has not much in common with this topic - the author mentions one of the things he learned early from his father: our actions lead our emotions. The emotions follow our actions, not the other way around. It is an important thing to remember. I'd even add that going the other way around, letting our actions to be caused by our emotions, leads to disaster in the long run.
Well, at least that's how it looks today. Tomorrow is another day...
