There are two currencies that, as a reader, you bestow upon me. If you are reading this, you’ve given me the first currency – time – and if you have been so kind as to buy my book, you’ve given me your cash.
This implies, I believe, an obligation on my part. And so here’s my promise: if you contact me, I’ll contact you back. If you ask me to do something, I’ll do whatever I can to fulfill the request. It might take me a day or two, I might not be able to do what you ask – but I promise I’ll try.
