1) Start a lucrative career much earlier. Money solves a lot of problems and makes life of much broader horizons. 2) Go out, date men/women as preferred, have as much exciting time and adventures as possible. 3) Move on from relationships that didn't work out as quickly as possible. Nothing is ever learned by crying over what is not there anymore. There is always something better waiting for you. And yes, you can let go of feelings. 4) Spend as little time as possible with friends/acquaintances who annoy you, conversations that aren't fun/interesting and go nowhere, attempts to convince or change other people's minds, especially partners and family.
