I just went to the kickstarter page:
https://www.kickstarter.com/projects/752968543/slipstream-time-hackingInteresting to see how he was inspired by the movie Interstellar to write this book. I loved that movie! Watched it twice, I don't normally rewatch movies.
Since it is so short, I will probably read it. But- it mostly looks like "do more in less time" philosophized as nearly time bending, which it is not. I get it for some things, but not for others. Yes, retiring early gives you the freedom to do any number of things that your longer working peers may not get to do. Obviously as a member of this forum I think this is great! And yes, you could get to and through parenthood faster by fostering a 3 & 5 year old, and it is a nice outside of the box kind of thinking, but average foster home stays are two years. I'm pretty sure fostering kids for a few years isn't quite the same as raising kids to adulthood.
But again, someone might say to me, "yeah, you can retire early, but doing it your way isn't quite the same as mine. I might be working until I'm 65, but I get to live in this mcmansion and have a full time nanny and cleaning person. You live in a small rental and rarely hire a babysitter and always clean for yourself" So I guess that's fair enough, it's not the same, and people can choose what they value the most and live accordingly.
Also, I have scanned it, and the writing is unimpressive. Honestly, I think it reads like an unseasoned blogger. Too many unnecessary modifiers, like a high school student trying to meet a minimum page requirement for an assignment. Also noticed a couple typos. Perhaps he should have raised a little more to pay for a better editor.
I am going to guess the full text of the book may be out there for exposure. This guy probably knows he isn't going to get rich or gain notoriety by selling this self-published book with B- writing. He's going to get there with exposure, Tim Ferriss style.
