Get scared. It will do you good. Smoke a bit, stare blankly at some ceilings, beat your head against some walls, refuse to see some people, paint and write. Get scared some more. Allow your little mind to do nothing but function. Stay inside, go out – I don’t care what you’ll do; but stay scared as hell. You will never be able to experience everything. So, please, do poetical justice to your soul and simply experience yourself.
