I'm not here to create an argument, but my life is GOOD based on the FACT that my MINDSET doesn't allow me to enter the norm bullshit that majority of people place themselves in, and that's all that matters (even with beating my shit).
It's all about how you take things in, and apply the negative into positive.
Give an example: Someone broke into my car, my family exiting out of our home to my car and see my shit is FUCKED UP, with all of my shit stolen. Do i get upset, and rage? No! I simply took it as an "L" and moved the fuck on. Mind you, shit got BETTER two weeks later (such a coincidence) when i got a promotion at my job and got a big check from my insurance company with the claim i put in. But I'm still beating my shit!!!!!
Perception is EVERYTHING, mindset is EVERYTHING. Don't teach one specific tool to have individuals believe this is the master key to that door they need to open. I'm Just SAYING!. Teach science, teach math, BUT NEVER TEACH MOTHER FUCKING PHILOSOPHY!
Majority of comments I've read so far is based on theoretical points that have YET to be proven for a "COMPLETE" understanding. I tell you what is proven, changing your negative mindset (whatever that may be), therefore it would result in positive outcome.
Have you looked into Stoicism? It is exactly as u are describing.
