RE: If you can travel back to any point in your life to give a single advise to your past self, taking into account the person you were, what advise would you give, and why you think your past self will listen?

Damn it Debbie, the boys' opinions don't matter and neither, the heartbreaks. Your breakdown for your finals is not the worst and really, boys are your least concern- because they're just boys. You'll eventually meet a man who'll treasure you but before getting to that, you'll need to strengthen your character and fortify your soul. Your Master's degree won't matter much (although I'd like to believe that it does) and you'll still be earning heck a lot without it. Most importantly, don't let society make you bitter and bitter you shall not become. Because that'll bring you down, Debbie. [monologue with self. And hell yes, I would even cash in BTC in 2008 or find more money to do so]
