A big long intimidating book on writing.
No, seriously, it is kind of long. It’s got 60 tips (at least) about writing.
I tried to make it fun, by telling some of it as story – books on writing are always so serious.
It has a LOT of great information in it, but it’s not a textbook. Don’t make it a serious chore, and don’t try and read it all in one go.
Seriously, read it casually, when you feel like it.
You might just find it helps.
