I would look at it from a habit forming perspective. I would suggest reading the book "The Power of Habit: Why We Do What We Do In Life" by Charles Duhigg. How we form habits and how we can change them is fascinating reading on it's own. This book takes a more scientific approach to understanding habit formation than other books of this sort tend to do. Read the book or just read up on the cue, routine, reward loop and how it can be hacked to change habits or form new ones. The author also goes into detail about how to build up your willpower, which will also help immensely. You've probably formed habits that have been reinforced over time that are detrimental to your goal of working on hobbies. This book can help change that.
