Which books? What are some changes that you've made?
I think the René Descartes saying "I think therefore I am" is important not in a sense of existing but of being conscious of yourself and your actions.
The idea of being someone is tricky.
We are many faces, I forget which philosophy says so, but I wake up happy 4 days in a row, the 5th I wake up sad. Why am I sad, my life is perfect. Why am I anxious, I have everything?
Different faces show each day, you have many faces, so you must learn to cope with them. You must learn to express them and control them, and harness them and from then you can learn about yourself.
I always say on thecoli "I've been learning muay thai for a year", always. It helps me, I'm not an aggressive person, I'm genuinely not an angry person. But with martial arts I learn about my aggression, about my anger, about myself.
Now I pick up the keyboard, I'm writing poems and songs and trying to compose melody's. This helps me delve into my emotions and my inspirations. I'm not the best, but yesterday I was thinking of writing a song based on DJ Quiks "Chocolate Lover", then I heard a melody in my head, it was from a Japanese hip hop song. I tried to play it, I ended up writing some lyrics about how this world tries to hold us down, on some change the world stuff. I didn't ever think I'd want to write songs let alone about changing the world. All I used to do was freestyle, I never learned how to sing.
I've written much, but basically what I'm saying is continue to read, but also learn new things. Learn how to play the guitar or speak mandarin or do kung fu, and through continuously learning you'll be able to learn more about yourself as well as better yourself
