I was 14. I had the same hobbies, like playing guitar and skateboarding and watching B-horror movies. But I was an overconfident jerk with a huge ego. I made YouTube videos 10 years ago, and looking back on them, I'm a more mature person, more educated and understanding now. I was one of those straight-edge-know-it-all types who think they're better than everyone else. I thought I knew everything, but I really knew nothing. One thing I had going for me was ignorant confidence. Blissful, youthful ignorance. I wasn't as exposed to internet forums, social media, psychedelia, self-awareness/consciousness, or even the sheer vastness of the universe. I also wasn't exposed to the corporate soul-sucking 9-5 job machine, either. So I was still naively motivated and excited for a "bright future" in every aspect of life (academics, relationships, career, etc) even though I wasn't that aware of the big, scary world around me.
10 years later, after several ego-death experiences, starting a band with friends, graduating college, many corporate soul-sucking jobs on my resume, and a ton of time to reflect all of my life choices ... I'm a much more open minded, laid-back and chill personality. I'm simply more likable to others now. I lost interest in trying to be "better" than everyone else, and instead started down a path that was geared towards my own creativity and self-reflection. I became a more diverse artist/musician, and started caring more about others around me. I essentially stopped being so self-absorbed and started looking at the world around me with more mature eyes, grateful to exist with my comforts and privileges. I'm still pretty young, so I have a lot to learn about the world, but I'm a better version of myself now than before.
