Colin Powell's 13 Life Rules For Any Future Leader

In his book "It Worked for Me: In Life and Leadership," the four-star general and former secretary of state shares the 13 rules he lives by and how he learned them. From staying optimistic to checking your ego, the tips and stories are useful and thought-provoking for anyone, veterans and civilians alike.

These were two of my favorites:

• "Things will get better. You will make them get better."
• "You can't make someone else's decisions. You shouldn't let someone else make yours."
• "Perpetual optimism is a force multiplier."
• "Have a vision. Be demanding."

The stories that follow the quotes are good, too. Read more at PolicyMic. (Thanks, Becky)
