This is it.

This is the day Marti McFly travels forward to: 4:29 pm (California time), October 21, 2015.

And this was the moment when I knew I was going to be a writer:

The pure joy that shot through me as the writers unveiled the time paradox, set off a bomb in my brain. I was, on the one hand, delighted that the explanation was so clever (I was a time-travel junkie, but I was only 17 and there was no Internet — at least not available to the general public — so I was not jaded by fandom’s endless discussions of the permutations of every plot trope ever).

At the same time I knew that I wanted to DO THAT: I wanted to give someone that moment of joy and revelation. I wanted to be that clever. I didn’t know if I’d ever be able to do it. But that was what I wanted to do.

This is why writers write: to invite people into a collective dream. To show off. To give people a thrill.

So go and write something!
