Show off your wealth. If you want to show off how much money you have, don’t do it by buying a bunch of stuff you don’t need. Instead, give money to charity or bunch lunch for the homeless guy outside your building every day. Show off your strength. If you want to show off how strong or manly you are, do it by protecting those that can’t protect themselves. Show off your intelligence. If you want to show off how smart you are, do it by offering to help people with assignments, using your intelligence to make things, or even by just admitting when you don’t know something (but offer to help them find out).
