While everyone overthinks situations once in a while, some people are troubled by thinking all the time. Overthinkers rethink conversations they had yesterday, second-guess every decision they make, and imagine disastrous outcomes all day. Their minds are like a movie where they imagine their car going off the road or they replay distressing events over and over again. 1.
Keep the focus on problem-solving
Keeping the focus on your problems isn’t helpful, but looking for solutions is. If it’s something you have some control over, consider how you can prevent the problem or challenge yourself to identify five potential solutions.
If it’s something you have no control over—like a natural disaster—think about the strategies you can use to cope with it. 2.
Schedule time for reflection
Worrying about your problems for long periods of time isn’t productive, but brief reflection can be helpful. Thinking about how you could do things differently or recognizing potential traps to your plan, could help you perform better in the future.
Add 15 minutes of “thinking time” into your daily schedule. During that time let yourself worry, or think about whatever you want. 3.

Entrepreneur and CEO of Tesla and Space X, Elon Musk may have a little more time on his hands, as he’s leaving his position on the board of the Open AI, according to a blog post.
The departure is likely the result of Tesla’s moving into the field of Artificial Intelligence(AI)，which he said in 2017 would be the “best in the world” and would even be able to “predict your destination.” Musk will continue to “donate and advise the organization,” Open AI said in a blog post on Feb. 20, adding that “As Tesla continues to become more focused on AI, this will avoid a potential future conflict for Elon.”
Musk and Y Combiner CEO Sam Altman co-founded the nonprofit enterprise in December 2015, its mission is to develop safe artificial general intelligence and ensure those developments are made public. Open AI researchers published a paper on the site ArXiv. Org, detailing the possible secure threats that come with “malicious” AI. In fact, Musk has heard of the “evil AI” alarm several times. On Aug. 11, 2017, he warned that artificial intelligence poses a bigger threat to humanity, and he told a gathering of state governors that the government needs to regulate AI before robots start “killing people. ”
Musk’s departure from the Open AI board could mean big things for Tesla. As Elon Goodbye, a financial reporter, noted on Futurism, the move “could signal that Tesla is more deeply committed to their own Al projects than we thought.” He added, “Those who have had their ears to any rumors that Tesla is ready to deliver vehicles capable of Level 5 autonomy could take this new Open Al development as a sign that the company is inching closer to that unapproachable goal. ”No company has reached that level of autonomy, which means that a driverless car could navigate any road under any conditions and that all the human “driver” would need to do is to input a destination.
