Here’s something obvious:
If you’re ever talking to a male or a female and they start up on some, “I don’t know why you like me, you’re too attractive/cool/funny/whatever for me” shit, they mean it and they’re doing you a favor.
If someone tells you they’re a loser, they’re not lying. Only a loser would feel the need to point out that they’re a loser. No one acts humble when they want to win.
So if someone says that to you, disassociate yourself from them yesterday. No time to build with small people.
