Oh lad,
I've thought, I went there prepared, because I was physically strong and had good mentality/discipline in daily's work. But...You know, we've participated in the battlegrounds with USA, Latvia, Germany, Spain, Italy and more! The thing is, when You sleep 5+ days in a row in the forest, when Your supplies at the lowest and it looks like everything is falling apart, then You know, that You are in the military, You need to say bye to Your health or other instincts (eating food, happy sleeps), to accomplish a task. It was incredible! ❤️ Glad, that You've asked ❤️
