RE: Persistance - 5 Reasons, why I will keep writing longer than YOU!
Thanks. I thought, it was my own insight, but thinking about it, it might be from Tim Ferris. He wrote somewhere about the phenomenon of an unfinished song being stuck in your head all day, because you haven't finished it.
Thoughts are the same way. If you write them down, they're finished and you won't have to keep bringing them up.
