It is a process that takes many years and much dedication. Most people expect to get better way faster than they do. Work through the lessons, taking at least a week for each of them. Play EVERY DAY. Make a video diary of your progress, at least once a week, so you can look back and see your improvement. Otherwise, it can be hard to notice, since there are little bits of improvement every day.
When you feel comfortable, post videos to YouTube and link here, and you will get helpful advice and positive criticism to encourage you.
It’s not easy, but it IS worth it!
