Advice for late teens/early 20s people - Dump loser friends now or pay later - Stack money - Be boring. You can party at 30 when your a multimillionaire - Work out like a pro athlete. Makes everything better long term. - Read many books
I would still advise them to forget pointless social stuff Especially now with the majority of the globe being ordered not to be social. Its probably not going to be an option soon, regardless if they want to or not.
