Will is applied to intent not the other way around. You can have the will to be successful, but if you don't create the intent on what and how to get there the will won't help. That's the way I see it. Wanting has nothing to do with it, it's what you intend to do that starts everything. But look at the different types of intent, there is natural intent, personal intent and the issue of competing intents.
Intent is the unyielding intention of doing X, it has to be built up and energy applied to it.
Seems every intent would need to have a priority. In a way it does in people. That is truly a mystery, the universe. Lots of times. Well, they are still spending energy on all those intentions.
