Articles/blogposts that changed how you look at business and entrepreneurship

I love reading about business, startup and entrepreneurship. I even started my own newsletter of the best articles I find everyday, as I’ve started hoarding a collection of good articles for a while, and I figured I might as well use it.

Recently though, I started having this burning question that I want to ask everyone.

What is an article(s) that you keep going over and over, time and time again? A piece of “magnum opus”, if you will. Something that was so good, so impactful on your journey, that you can’t help but keep re-reading it?

I’ll go first. The best article I’ve ever read is this one by James Altucher. It forever changed the perspective of what entrepreneurship is for me and how I look at ideas. I think it boils down to this simple concept: don’t have an idea, have 10.

So what’s yours?
