When taking on something new, I always break it up into pieces and learn a chunk at a time. Once I've conquered a chunk, I piece it together with the next one rather than trying to take on the whole piece at once. If you practice something difficult for 5 minutes remember to practice it again the next day and soon it will not be difficult and so on.
It's much easier to get on the roof stepping up a ladder than sprinting across the lawn and making an out of control leap for the gutter. Just make sure that each step of the ladder is sturdy and you will reach your goal.
