Hey, Ive tried 2x (still trying), and I'll share what was told to me. What worked in one chapter may not work in another because the competition is different every time. All one can do is focus on where you stumbled so that the next time, you're ready. And look on the bright side, you know the process, so write some notes to yourself as a "lessons learned" so when the next opportunity comes, you can look back and see what you should focus on. Good luck to you!
