"He who has a why to live can bear almost any how."
- Friedrich Nietzsche
This ability to innocently, and consistently, explore the world wanting to know why things exist or work the way they do is lost to many adults. The only time a child asks "how" is when you completely stump them (as in a magic trick).
In college, you should rekindle that burning desire to understand and ask why rather than how. The how will fall out once you understand why certain actions are taken or why a specific concept is needed.
My Style: I teach mathematics from a conceptual point of view. I do not like to teach shortcuts or algorithms, so my students should not expect a recipe of how to solve individual problems. Instead, I assume that you, the student, can derive a shortcut that works for you. This is a win-win! You have a solid, core understanding of why the mathematics works from the lecture and you have discovered on your own a shortcut in your own terms.
