You cannot fix your problems by throwing money at them. If you’re a miserable sourpuss who is convinced that you’re a blight on the universe, your self-esteem isn’t suddenly going to improve because you have a lot of dough in the bank. If you are a homebody who always complains that you don’t have any friends, a generous stock profile isn’t going to make you a fun hang. There’s a huge group of men online who think that money would solve all of their dating problems, but that’s just not true.

Would you charge your mom rent if she kept getting herself into bad financial situations? Would you have the gall to kick her out if she failed to pay her portion of the rent?
