You can see the determination in his eyes
That's the way a friend described someone she had just met. She was sure (just as I'm sure) that he's going places. Once the determination is in his eyes, the learning will take care of itself.
On the other hand, if I can see the fear in your eyes, then I'm not sure that learning alone will take care of the problem. No one can prove that the path you're on is risk free or guaranteed to work. Searching for more proof is futile. Searching for more determination makes more sense.
