I've had this conversation with 3 friends in the last few weeks about how to actually get great content for your book. I call this excavating your soul. If you look to the actual setbacks that you have and build your insights and lessons on this, you will have a useful story to tell. It will also be a huge source of personal development which will build your faith and confidence in your self.

The easy way to do this is when you are down cycling, depressed, or failing, keep a journal of it. It will suck in the moment, but when you get out of your spot, you will have a great book waiting for you. Listen in and I will tell you some stories about how I found this.
