@cell @kaia I think it fosters something in your mind that I think is a misunderstanding that's bad for your character and for success: That being successful involves being 'bad' or 'evil' somehow. The best way to be successful is to provide the most value to the most people, not to trick and cheat. Having the 'I would be succesful if only I wasn't such a good person' meme makes you resent succesful people ("she could only get there because she doesn't care about morals"), makes you lethargic by giving you a good excuse to never do anything ("i'm not doing well but that's to be expected because I'm a good person") and prevents you from learning from others.

I think you should always try to be as morally correct as you can be in whatever you do, there's no special dispensation for 'business'.
