It takes time, so give it ample amount of time. You won't learn in a day.
The more you give in, the more you get. Within that time, know your instrument. Passionately connect, so you don't want to keep it down. And thus, your practice more, and you get more. But be patient, persevere.
There's more music than what's in the books. Music existed before them. So keep in mind that you need to focus on it as an individual learner.
