A big part of abstraction for me is bringing problems into something I can visualize. This reduction itself works better if I have visual intuition. I suppose linear systems are a simple case, since their functional behavior for finite dimensions can pretty much all be mapped into 3D (I guess 4D would be a little richer with double complex eigenvalue pairs, but that's just 2x 2D rotations). I don't claim to be a great problem solver, but I've gone halfway through college so far with pretty good grades without changing how much visually I think.
