I guess it's just a matter of making sure you are doing things you enjoy as well. Some songs can get tedious (my teacher had me skip songs because of that at times) and this is where having a teacher can help. Mine had been finding me other books to try and asked me up front what music I wanted to be able to play. While I'm not exactly playing Hans Zimmer music yet she does try and keep the repertoire interesting and fresh week to week.
This is my beginner star wars book I'm learning from (slowly)
