Lessons Learned: The Lean Startup Book is here 15 years ago
Wait...so a self-proclaimed start-up guru dares to profit off of his own work?
If you run a company (and Eric Ries does too, don't forget) and you don't spend a significant portion of your time self-promoting, if you aren't telling everyone you know about what you're working on, and if you don't take credit for your product being the best thing since the iPod, then you're probably not going to do very well.
I am looking forward to reading his book and excited for it, but he's not an magic oracle or a god. Your own success will still come from how well you do (or don't) you apply his (and every other author's) lessons to your own business.
Keep up the good work, Eric.
