There’s no other book series I am more excited about than the one by 99u. Every single one so far has been rock solid, full of super-useful, actionable advice. Volume Three, Make Your Mark launches tomorrow and I am lucky enough to have gotten my hands on an early copy. (And was delighted to discover that Shane Snow wrote a chapter for the book that talks about how we try to sprinkle some love in all things we do at Tattly!)

The contributor list is super impressive; Keith Yamashita, Seth Godin, Jane ni Dhulchaointigh, John Maeda just to mention a few. There’s nothing I value more than advice and insights from people that are doers, getting their hands dirty, building and defining companies, making it all happen.

Make Your Mark, and the two other books in the 99u series, are business books for makers, not managers. In Make Your Mark Jocelyn and her team tapped 21 leading entrepreneurs and experts to share their best practices for launching a purpose-driven business, refining your product, delighting your customers, inspiring your team—and ultimately—making something that matters.

You can pre-order the book here or share the best advice you’ve ever been given in a comment below to enter this week’s Make Your Mark book give-away. 10 winners will be randomly chosen by the end of the week and will receive a copy. Yay!

And yes, hell just froze over; Nine years in, this is my first ever give-away on this blog. That’s how much I love (!) this book series.
