We can learn a big lesson as leaders, entrepreneurs, and managers from these words of Eleanor Roosevelt: "Do one thing that scares you every day."

Being a leader is sometimes frightening. There's often something out of control--out of your scope, out of your realm. If you're constantly fighting these things, you can't change. You're not only fighting a losing battle, you're also subverting your own growth.

But by taking on the challenge of doing one thing that scares you every day, you can create opportunities and reach new achievements.

We're all afraid of something--the challenge is to try one thing every day that scares you.

Start small and become more daring. By taking small risks on a daily basis, you will notice that every time you do something that scares you, you diminish your fear a little bit.

Take the challenge, and for the next 30 days, commit to doing things that scare you. You can use these examples, or make up your own:

Take the 30-day challenge and share your bravery with us at Inc. and my Twitter feed. Tweet us your daily examples of courage and it will accumulate in a bold 30 days.

Share your fearlessness with us on Twitter with the hashtag #Bold&Brave and ping me at @LollyDaskal.

Let's start a movement of challenging ourselves to challenge our fears.
