I find it difficult to live by the mentality "not give a fuck" because I believe it's just a cop-out in ignoring your emotions. Everyone should try and understand where your emotions fundamentally come from. Having said that, what do YOU think is necessary to regain your composure after a bad incident (getting shutdown, dumped, bad date, etc). I understand how everyone should try to be outcome independent, but how do you withhold that mentality without completely neglecting your emotions?
