Sometimes you have to say no to your friends to say yes to your work

It's 23ºC here in Tel Aviv. I'm sitting outside my dorm in a T-shirt and jeans, headphones in, working my way through a draft of the forward of this book.

I think some friends of mine are going to a bar with live music in southern Tel Aviv, near Jaffa. I'm probably not going to join them -- part of it is residual tiredness from traveling all day Thursday and not getting into Tel Aviv until 5am on Friday, but part of it is that I'm working on the book. I have an idea of how I want this forward to look, and so I'm probably going to keep at it until what's on the page looks a little bit more like what's in my head.

As I was working, I was reminded of an answer Lin-Manuel Miranda gave in an interview about writing stuff. He's asked if the idea of writing Hamilton ever got overwhelming and whether he ever thought about giving up. He says:

Oh, all the time. All the time. And then you push through it. Like, you push through it because what’s the alternative — you’re going to just leave that idea stuck in your head forever? That sucks. The alternative is you go through life and you had this great idea and nothing came of it, because you got tired? And yeah, sometimes you don’t go to the party that all your friends are at because the idea is calling to you in that moment.
You have to do that sometimes. You have to say no to your friends to say yes to your work. Because, what are you going to do? Lose that idea because you decided to have a drink with your friends?
