Losing strengthens you. It reveals your weaknesses so you can fix them

I mean, we're always trying to evaluate and tweak things and get better.

There is always someone better than you. Whatever it is that you do for a living, chances are, you will run into a situation in which you are not as talented as the person next to you. That's when being a competitor can make a difference in your fortunes.

In order to grow, you must accept new responsibilities, no matter how uncertain you may feel or how unprepared you are to deal with them.

Teamwork does not come naturally. Let's face it. We are born with certain inclinations, but sharing isn't one of them.

Accountability is essential to personal growth, as well as team growth. How can you improve if you're never wrong? If you don't admit a mistake and take responsibility for it, you're bound to make the same one again.

The absolute heart of loyalty is to value those people who tell you the truth, not just those people who tell you what you want to hear. In fact, you should value them most. Because they have paid you the compliment of leveling with you and assuming you can handle it.
