If you have fear of some pain or suffering, you should examine whether there is anything you can do about it. If you can, there is no need to worry about it; if you cannot do anything, then there is also no need to worry.Dalai Lama
Therefore I tell you, do not worry about your life, what you will eat or drink; or about your body, what you will wear. Is not life more than food, and the body more than clothes?Jesus Christ
Worrying doesn't change the future; it only exacerbates our problems by leading to anxiety, stress, and physical health issues. Worry, in essence, is a futile endeavor.Rob Burbea
We overestimate the size of our problems, which makes worrying about them seem reasonable.Adam Mastroianni
