Here's a terrific article about my friend Jeff Kinney on his current best-selling book tour. Jeff's sold about 300 million books--that's not hyperbole, it's the actual number--and I think writer Mitch Wallace captures just the right tone explaining why that is, what Jeff is like, and what it feels like to do these events.
In fact, his article reminds me of blog posts I wrote in 2009 (!) and 2013 about earlier Wimpy Kid book tours, back when Jeff toured in a luxury rock star bus (IIRC, the previous tenant of his bus was Pink) that he's since simplified to a big van. I think the downsize suits him. I'll put a link to my post in the first comment.
One other thought: Jeff works really, really hard. In fact, I'm lucky enough to know a few very successful authors, and the quality they have in common is they all work hard. Which isn't to say that less successful writers aren't working just as hard, but I don't know any who are sitting back and phoning it in. They all care, they want the next thing to be better, they sit down and grind.
Life lesson. Do the best work you can, then learn and try to do better.
