They are different things. There is lots of research in self regulation and it boils down to (unsurprisingly): the most efficient and elegant way to self-regulate is to avoid continuous self-regulation, i.e. create habits. There is also lots of research on how to create habits :)
A good summary of current state of research is "A handbook of self-regulation", edited by Roy Baumeister, but it's definitely not an easy read. It's amazing though to find out exactly how far we've come in understanding these things - and it's also pretty exciting how recent most of it is.
There are more practical books out there, drawing from the same research. "The Procrastination Equation" by Piers Steel is the best I've found so far.
