Looking back, I regret very little. I really did play the hand I was dealt as masterfully as I could with the resources, guidance, and understanding that I had at the time. I overcame (to a degree) my abusive childhood. I got to see the world. I jumped at a lot of opportunities that I would've regretted not having done if I hadn't. At the time, I thought life was worth living. I guess, for me, living just changed my perspective. When you're young, you view life through the lenses of hope and optimism. When you're older, you view life through the lenses of experience and hindsight. So, unless one just has an undying love of life, it becomes very difficult to muster the same enthusiasm for life after a certain age. While I do lend credence to chance, hope has all but died in me. Not because I'm sad, or angry, or even disappointed. But I have a 20-year sample size of adult human life. That's enough for me to gain a fairly reasonable perspective on life and its unfortunate realities.
I guess if I had one regret, it would be not ending it sooner. Not because I didn't enjoy the ride, but because nothing changed enough for me to change my mind about ctb from age 18 to now. For me, it would've been just saving myself from the inevitable anyway. However, I don't regret experiencing my 20's and 30's either. This regret is made through the lens of hindsight. I would suggest just doing as much reflection on your life as you can. Get a little insight into what you think your life will be like. Try to create the kind of life you think you want, if that's possible. Above all, just do your best. If catching the bus is right for you, then you will reach that conclusion eventually.
