If you didn’t give a fuck about losing anything in your life, and were ready for it, it’d be impossible for anything to shake you, make you feel down or grieve its loss.
Passions can be dangerous, as a passion can bind someone so closely to something that should it disappear, leave or end, chances are it’s going to affect you in a major way. So if you prepare for (or even expect) everything you have to end (as it will), it’s possible to live a life of complete level-headedness and balance.
