My goal is to be as helpful as possible to as many people as I can, so I have pulled together on this page the absolute best and fastest ways to reach me and/or work with me about literally anything I can imagine. To that end, please look carefully through all the options below, and you are 99.8% likely to find the shortest of shortcuts to get exactly what you need, virtually immediately. You’ll see how to pitch me, get advice, work with my companies, book me as a speaker, follow my activity, have me inscribe a book for you, learn about my hobbies…even record a birthday greeting or an inspirational pep talk! In my experience, these routes are, in each case, MUCH faster than generically trying to email, text, or call me and getting lost in the weeds. (If you think that may be an exaggeration, just realize that as of this writing I have 93,329 unopened emails in my inbox :-(
