Worrying is a form of psychological friction
Worry is an anticipation that things are going to go wrong (we don’t worry about things going right). Whether you try to control your life by worrying, over-thinking, ruminating, being too cautious, fearful, or doubtful, worry isn’t the answer. If you’re stumbling emotionally in life, then incessant worrying may well be the root of your problem.
Rather than worrying about an uncertain or chaotic future, stay focused on the here-and-now facts of your life. If, for example, you have high cholesterol (which would be a fact), rather than worrying about having a heart attack, address the facts by eating more healthfully, getting more exercise, medication, and so on. Dealing with facts keeps you effectively in the present with a bonus of eliminating the anxiety associated with anticipating doom and gloom.
