Books.

... I wanted to be a writer. 30 short stories, 3 abandoned novels, and over 100 rejection letters later, at 18, I gave up.

Great! I have a desire to write historical novels (or atleast documentaries related to history) but scheduled to do this in my 50’s (now I am 33). It really requires such looong plans and experience! I used to write and illustrate for comics books in my teenage, somewhere I lost and gradually caught with long future plans!
