Kinda a trick question OP.
Lately I've been under the belief that every experience we have has two outcomes. One that makes you bitter and one that makes you better.
My entire life has generally been nothing but failure. But that's okay, because I refuse to give up on my dreams and goals.
I've done things outside of my dreams and goals that helped me become a stronger person, but doesn't necessarily made me more of a man.
I've done a solo backpacking trip through Alaska, learned to fly a plane, learned How to scuba dive, climbed Mount Whitney, started two companies, almost got married to an abusive bitch, pulled a gun on a home intruder and almost killed him, almost killed myself due to failure in said companies and school, and etc and etc. (All of this besides getting married and starting two companies are things I've done this past year)
Do these things make me a man?
Nah, I don't think so. Do these make me a brave and stupid badass? Nah.
But the confidence and experience that came with it helped me find my way of being my own unique person.
I'm still trying to become the best user I can be. I still want to be that kind of individual that people envy through hardwork and determination.
Be kind, respectful, fierce, confident, intelligent, attractive and motivated, and soon you'll discover that you can essentially accomplish anything.
Best of luck with your adventures and life OP. Good luck with the Marines.
(I always wanted to be in the military. It was my dream as a kid to be a Green Beret. But the military wouldn't take me due to my deformed flat feet. So instead, I chose my own path.)
