How do you guys motivate yourselves into getting good grades in painfully boring stuff like multivariable calculus or deriving algebraic rules? Is there a trick to it that I don't know?

I hate it so much when this happens. There's little anon with his problem, and out comes my person with the most disgustingly basic counterexample to rain on his parade.

A'ight, so I figured out that Galois's intuition for group theory is actually the best thing since sliced bread and working with groups as permutations on a random set X allows me to do amazingly pretty stuff such as treating isomorphisms and homomorphisms as other permutations on X.
But I've got absolutely no idea how to extend this intuition to multiplication. Thoughts?
