From my own experience, the fastest way to learn is to think of some project you can be passionate about and start getting your feet wet. Start with something simple, and don't worry if it's already been done, go and do it your own way. When you have a vision of how you want something to work, that becomes the driving force you need to go out and find the resources you need to get it done, rather than stumbling through exercises with no end result. To me the difference is like riding my bike outside on a nice day to get a workout, and riding a stationary bike indoors.
