There is a moment in your life so vivid and lucid, so it changes your perspective, belief and value completely. As if the experience not only changes your life but also changes everything you see and feel from there on.
The "moment" lasted 10 days for me. The experience of that creative workshop gave me a whole new perspective as a artist/creator.
It's not about what I learned new things. Most of the things I already knew. It's just I realized I had all of those and now I know I can express those.
