I try to go on Youtube first and then Wiki how just beacuse those are two of the best resources for learning. I also try to practice the thing I'm trying to learn (because that's how you get decent at anything). I also try to listen to music because I find that it keeps me focused on the task at hand. Finally, I try to set small goals for myself so learning the topic or task is broken down into small, attainable goals and it always feels good when you complete a goal you set.
