Memos to Dan is a very practical book – and its practical parts, I must say, are truly excellent. Entrepreneurship is hard to teach effectively because every entrepreneurial venture is patently unique.  However, Memos to Dan balances specific examples with a solid conceptual foundation to make its lessons highly generalizable. The sections on family business are fascinating – especially when it comes to how and when to navigate the often complicated transitions of a company among family members. The information about mentors is extremely novel – I had never thought about engaging vendors as advisors, but now I will utilize this notion in my own lectures and consulting work. The book’s organization is fantastic – it includes a large number of short and specific chapters that make for a very useful handbook.
