Here are four thoughtful tips to help you stop negative thinking. Sometimes, the world can feel stressful. When things are out of our control, we may start to think negatively. But don’t worry — there are good ways to deal with it.

First, try a “No Complaining” challenge. Try not to complain for one whole week. Every time you complain, you have to start the count again from Day 1. You might be surprised to see how much time you spend thinking about things you cannot change.

Second, stop asking “what if” questions about bad things. Instead, ask yourself, “But what if everything works out well?” When you start to worry, make your brain think about good results with the same energy.

Third, use the 10-Second Rule. When a negative thought comes, give yourself 10 seconds to decide if it needs your attention. Ask yourself: Is this thought helpful? Can I do something about it now? If not, let it go.

Finally, stop rehearsing disaster in your mind. When you always imagine worst-case scenarios (场景), you are training your brain to expect disappointment. Try to picture things going well instead.
