What I did was have a word document on my phone that I named Book Ideas. I actually was planning to do a fantasy/science fiction novel. I have quite a few notes on that, however I decided on another. I have plenty of notes though. I've been thinking about the book ideas for about 8 months now. I don't think many people can just start with a blank slate and write a decent book. It took time for me to settle on this idea for a book.

Do you have a note pad on your phone that you could use each time you are inspired? Once you have an idea for a book, then ideas just burst out each and every day. which is where you want to store your ideas on a phone/notepad. The next hardest part is how to start it. Once you are able to have an outline, for me, everything falls in place. If im stuck in one section, I can go to the next. The point is to keep moving through it. The best part is tinkering with it. Moving, molding, and giving finesse is really fun. You'll catch yourself using words you never used. It's really interesting. Plus, you can use alliterations and end rhyme to engage the reader.
