These are worth repeating until they’re burned into your heart and on your brain. 

Dale Carnegie had a lot of good ideas about living a better life. I’ve shared these before. 

So practical and simple, and timeless, really. Here he shares some fundamental facts about worry and how to transcend and overcome this universal human emotion:

1. If you want to avoid worry, do what Sir William Osler did: Live in “day-tight compartments.” Don’t stew about the future. Just live each day until bedtime.

2. The next time Trouble–with a Capital T–backs you up in a corner, try the magic formula of Willis H. Carrier:

a. Ask yourself, “What is the worst that can possibly happen if I can’t solve my problem?

b. Prepare yourself mentally to accept the worst–if necessary.

c. Then calmly try to improve upon the worst–which you have already mentally agreed to accept. 

3. Remind yourself of the exorbitant price you can pay for worry in terms of your health. “Those who do not know how to fight worry die young.”
