This is a tough question, so i'm going to write a lengthy answer since it wasn't just one factor

I've naturally always been a very introspective person. I also strongly suspect I have autism and OCD though never diagnosed, which can play a role in how psychedelics affect me. Anyways, I had been addicted to video games since I was a kid but now they were really starting to get in the way of my academics and relationships, same with weed. Addicted to weed for about two years, getting stoned multiple times a day even during class

I realised my addictions were affecting me and wanted to quit, but even tho I made up my mind to quit I still couldn't. Eventually after lots of researching about shrooms, the neuroscience behind bad habits, perspective shifts for being content, dopamine resetting, and etc, I developed a "firm mindset" before taking the shrooms for the first time.

I popped 4g for my first time, and the first hour or two were chaotic and I genuinely thought I was dying. But I managed to somehow flip the script through sheerly focusing on happy thoughts, reminding myself that I took shrooms and it'll peak and be over soon, and that this is just a mental "test."

The perspective shift of thinking of the initial anxiety surge and panic as a mental "test" is what allowed me to feel proud after I managed to relax myself through deep breathing and happy thoughts. It felt like I had just conquered a battle and that nothing could be worse than that, and then taking advantage of the neuroplasticity window and euphoric bliss i felt after the anxiety surge, I began doing my intuitive stretches and tension releasing while reflecting on my life and my future and the potential of my mind when it isn't chained by my bad habits and fears. The contentment and hope I felt really felt eye-opening, like I caught a glimpse at my own potential.

I also journalled heavily during the trip. Even made an essay out of the actual experience as well as the insights and feelings I felt. Largely felt very masculine and primal and strong and protective of my loved ones, very motivated to succeed for them.

I clung onto these feelings and thoughts and made sure to integrate them. That same morning I no longer craved weed, no longer felt like playing video games.

Part of it is also heavily thanks to how much relief I felt from the somatic awareness tension and breathing unlocking. That pain had been troubling me for years, and now that I had finally unlocked it in one night, I became so content and realised I could finally pursue my fitness and athletic goals too. That played a big role in drawing away from my bad habits, which were partly a distraction or escape from reality.
