I actually find "Money and chicks" to be an overwhelming goal for most of my characters. Or sure, "power" is up there, no doubt - who doesn't want that, eh? "Chicks, money, power, and chicks" and whatnot. But idealism in the face of twenty levels of dungeons, traps, mad wizards, and death? Glory don't sell for much.
My last character before my current one was a simple militia-man who was tired of risking his life for such little pay, so he took to adventuring. Not for the good of the world, or for the good of the city, and certainly not because any gods gave a reason (Them bastards never help us common folk, what!) He did it because adventurers always have the nicest clothing, they throw gold around like it's no big deal at the tavern, they catch all the elf skirts, and to top it all off, they even have a chance to get brought back to life if they go down! Huh!
