What's the Most Challenging Part of the Process?

i have questions about book writing and book selling. So what was the most challenging part of the whole process? i had to build a google calendar just so that all the people booking me to do appearances could have a place to put it, so that it wouldn't overlap. I did like, 19 interviews on the day of the book launch. It's different than, like, nobody has gott me to shut up yet in my life. Riyou can you ask my ex wife, either the a number of people you could ask in the world, cristir while is fairly unshut upable.
