Excellent advice in all areas. My concern is that advancing so quickly (7 days), or even in a few months, is not going to provide enough different experiences. The various seasonal conditions U/W, changing currents and different types of currents, and helping students learn to recover from mistakes all take considerable time. as does gaining experiences in unique dive sites where you'll someday be taking OW and AOW students yourself as an instructor. Not to discourage anyone from pursuing DM level but I wouldn't have confidence in hiring one for my classes who hadn't gained a LOT of knowledge and experience before certification.
My suggestions: Expect to work with 20 or more classes from basic through the specialties and rescue, Take trips to a handful of dive locations around the world to experience their unique problems as well as enjoy them. Travel to dive sites where shore entry subjects you to riptides, large waves and rapidly-changing surf conditions. Dive in remote locations where towns and medical assistance aren't nearby. Do some blue water diving to gain skills that increase self-reliance and self-rescue so that you can better teach those. And most importantly, enjoy every moment, for as Dive_Master Tom said, it isn't a destination but a journey. A journey like this would be a huge asset to any instructor or shop.
