This should be an easy one for you. Volere e' potere- to want (something) is to be able (to do it). This is obviously the equivalent of "where there's a will there's a way." Both words are infinitives, and "potere" is also a noun meaning "power."
Hmm. Don't know about this. Seems to me that there are way too many variables outside one's control to make simple will the sole or even primary factor in getting what you want or even need. Although will and determination are certainly very important. My verdict on this proverb: a good deal of truth, but overstated.
