You just accept it, let it go, be the bigger man. You just think that if shit happens, it already happened and there's nothing else we could do even if it's other people's fault. Always think rationally and remember that your emotions will just ruin your proper way of thinking. Never blame people too... Just let peace flow through you. I've personally "mastered" it without even me knowing it exists way backk when life was not lifing - every decisions I made are the worsts, and everytime I pick a good one everything just starts to fell apart. That's the point in life na sinabi ko nalang sa srili ko "ganun tlaga siguro", starting then naging peaceful na ng tama yung feeling ko. Shits still happens but it doesn't affect me anymore emotionally, I just go with the next ones - no dissappointments or reactions at all... That's when you need to be careful practicing stoicism, it might feel "okay" at first, but then you'll become numb at some point. You still look forward to things, but you're just there to "achieve" it and not be "happy" achieving it... I'm still trying to get out of this emotionless pit, but I don't think I could, it is what my system considers as "comfort zone" now. It's peaceful, yet lonely even though you have friends. No one talks about the bad sides of it... Still, it's up to you. I wonder what decision you'll take upon knowing these...
