I'd rather do the right thing and be happy with the sort of person I am (albeit a poorer one than I could be) than be little more than a thief, deeply unhappy about what sort of human I am but have a few extra quid in my pocket
It honestly never ceases to amaze me how ready people are these days to suspend all sense of morality in the pursuit of making themselves a little bit more wealthy. Is it really making you happy, giving your life a sense of purpose and meaning? I find it impossible to believe.
