Music is forever, a constant learning experience. One year or ten wil not define it. Just don´t forget that although you need to know your keys, chords and dominants, music is really more than that, music is feeling, is heart. One day at a time. I have experienced similar sentiments, wanting to know everything, but then I remember that it is not all. Enjoy your musical journey, that´s the secret, and that´s what I tell myself. And here I am, 40 years "into" music... Cheer up!
