Here's a nerdy way to rephrase what was emphasized in Dale Carnegie's bestseller How to Stop Worrying and Start Living.
The future, no matter how overwhelmingly pressing we think it is, we have neither write or read access to; The past, we have read access to, but not write access; only the present do we have both read and write access, and therefore it is our only game to play, our only universe to participate in, for real.
I was disheartened by my flaws, and I thought I was not meant to get involved in anything, that way, nobody can possibly get hurt. Indeed that is true, and that's why it is so toxic of a mindset.
But then, hearing a wise word from a friend, and practicing guided meditation with Sarah Blondin, I started to wake up over time. It was exactly the point to start as flawed, and then grow towards a better self, the soul has to heal, expand, mature, and it is this positive delta that we strive for. And "we grow from pain". If we stop making efforts to improve, just because we found ourselves lacking, selfish, lazy, stupid, weak, then that is the worst thing we can do, to both ourselves and to the world around us. We owe the world (the good people in it) to evolve, to rectify, to transcend. The metamorphosis of the soul, so to speak.
In fact, if someone hypothetically were born perfect, that would be actually pretty depressing of an outlook, as I noted earlier, because that would mean, any deviation, any effort of change, would be, by definition, a fuckup. If staying the same is the absolute best thing one can ever do, then it is essentially death, the opposite of life.
So, go and live a life. BTW, you've already learned so much, apply them. You have Guo, Kara, Ellie, and all the kind and wise souls in you. You are not alone.
