That is either very wise or complete and utter nonsense. The line between profundity and hogwash is damn fine.
Well it's amazing what people with strong will can accomplish. Just look at Stephen Hawking for example. He can hardly do anything but he does have his mind, and he's used it to do great things, he's certainly accomplished much more than many other people have even in his state.
Perhaps it depends on the situation but basically if you have enough will to do something great then with even the smallest amount of options, if you use them right you can do great things.
