Ryan Holiday said this quote

The combination of power, fear, and mania can be deadly. The leader, convinced that he might be betrayed, acts first and betrays others first. Afraid that he's not well liked, he works so hard to get others to like him that it has the opposite effect. Convinced of mismanagement, he micromanages and becomes the source of the mismanagement. And on and on - the things we fear or dread, we blindly inflict on ourselves.

Let others slap each others on the back while you're back in the lab or the gym or pounding the pavement.

Doing great work is a struggle. It's draining, it's demoralizing, it's frightening - not always, but it can feel that way when we're deep in the middle of it.

~ Ryan Holiday

The question to ask, when you feel pride, then, is this: What am I missing right now that a more humble person might see? What am I avoiding, or running from, with my bluster, franticness, and embellishments? It is far better to ask and answer these questions now, with the stakes still low, than it will be later.
