Is it really true that you should not do magick for personal gain? It’s not wrong to want a better job or a promotion, though it would be wrong to hurt an innocent person who is your competition. There’s nothing wrong with wanting to pass a test, though it would be wrong to cheat. There is nothing wrong with wanting something, there would be something wrong with stealing it. So using magic to help you get ahead, to be alert and on your game, to get things you want— there's nothing wrong with that. As long as you’re not trying to go about it by mowing down innocents, cheating and stealing, there’s no ethical dilemma here. However there are things to consider and ways to go about it responsibly.
