"So I resolved myself to not lose faith until I get to what I'm aiming for."

This is called perseverance and in my opinion it's much more important than faith alone. Even if you lose faith from time to time (because it happens for short periods, no matter what you do), you have to keep doing what you do in order to reach your goals. Consistent action, practicing every day, learning and trying new things; I think these are the most important things.
