heh, the answer is that: yes attacking from many places at once/harassing is a very good general strategy. It wins economically, especially if you try to counter it by playing defensively (eg tracking down all the various attackers). The best defense against this kind of attack is to mass your troops, and march them straight for the enemy capitol (or nearest convieniant castle)... assuming you start with a comparable force of troops, you should be able to defeat his fragmented forces in any province of your choosing... eg his home, and this is usually enough to combat the economic losses of his pronged attack.
