You'll need to do three things when studying or learning a new skill:
1. Give your mind a ton of material: This might seem obvious, but immersing yourself completely in what you're trying to learn is the first step to actually learning it. You don't have to actively try to memorize things, just expose yourself to the skill or material as much as possible.
2. Practice: We tend to stop practicing a skill or stop studying when we think "we've got it." However, well after we learn something we still continue to refine that skill.
3. Sleep: It's thought that sleep is essential to learning and remembering. Some studies have suggested that the brain identifies patterns in our memories and consolidates them to make them permanent when we're sleeping. In essence, a good night of rest might be better than an all-night study-fest.
