You have to do this every day. Keeping the thoughts in your head without writing them down is suffocating, like keeping the windows shut. The buildup of exhaust will kill you, smother your ambition, crush your hopes. The only thing to do is the hardest thing to do: keep up with the effort. Keep going even when there is no hope anymore. Speed down that tunnel even when you see no light at the end of it. The fire has to burn within you that there is something there at the end, that you just have to keep going.
It will still come to you, it can still come to you. Remember the little fisherman of the night, the spider in the cup. Every night, spin a web. Every day, write something. The way is there, you just need to find it.
