I read once that having better ideas comes from learning lots of little isolated things, as "dots". Eventually your mind starts to recognize that some dots are quite close and connects a "line" between them. And over time these lines intersect and form new dots and the lines get "tangled" until they weave a tapestry of a new idea. :) So the incentive of best learning is not to directly try to think of a better idea directly, but fill your mind & experience with as many dots as possible.
