> Winning wars seems more interesting than having great teams.
It's ok to write blog posts about a variety of things, even if you think there's something potentially more interesting elsewhere.
I would like to point out that having a great military force is not enough for what's important -- many times, it's not even needed!
This is a guide for those who have decided on their own that they want to focus on building a great team, because their personal assessment is that a great team is what they need to succeed.
