Don't just sit there and worry. Be proactive. Do something - anything - about what's worrying you so you can gain information, focus and control over the situation. I've suffered a great many catastrophes in my life. Most of them never happened.
If a problem is fixable, if a situation is such that you can do something about it, then there is no need to worry. If it's not fixable, then there is no help in worrying. There is no benefit in worrying whatsoever.
When a man points a finger at someone else, he should remember that three of his fingers are pointing at himself. Do not worry about your difficulties in mathematics; I can assure you that mine are still greater.
I urge you to live within your means. One cannot spend more than one earns and remain solvent. I promise you that you will then be happier than you would be if you were constantly worrying about how to make the next payment on nonessential debt.
I don`t know if Donald Trump`s ever been to an actual polling place, but, you know, he doesn`t even worry if what he says is true. This is just about him worried that he`s losing.
I have spent most of my time worrying about things that have never happened. Worrying is not an action! In fact, it is action that alleviates concern and dissipates worries. Take more actions when you feel that worry is creeping in to steal your time. It need not be a huge action, any action in the direction you want to go will do.
