Well, for things like computers, I always find how is easier than why, I can figure out how to use a program quite easily, but I wouldn't be able to read the source code, learning computer languages is hard work for me, but that doesn't stop me trying

Electronics, strangely enough, is another matter, I know about electron flow and magnetic fields in a 'behaviour' kind of way, but if someone gave me a field strength, a resistance, a current etc and asked me to figure out the ampage required for it, I wouldn't have a clue, I know why, but I don't know how.
It all depends on how you visualise things I suppose.
