Almost too many of us identify as overthinkers. Mostly, it is just an idle mind playing game but sometimes it is also linked to depression and anxiety that we may have failed to recognize. In any case, overthinking can really bring your morale down. Those who do it often know how taxing it can get for the brain to live in a constant state of negativity and worry. You forget to live in the moment and you just can’t stop conjuring up the worst possible scenarios for problems that don’t even exist. You may think it is impossible to stop overthinking, but it can actually be done with the help of a few habits you must master over time.

• Every time your mind starts wandering off to overthink, consciously bring it back. You must exercise extreme control over your brain, concentrating on the moment at hand. Focus hard on the work in front of you and each time your mind starts veering again, firmly hold it and bring it back. This will keep getting easier each time.
• Meditate for increased concentration. Practice breathing exercises and devote some time to this every day. When you’re meditating, your mind focuses on a particular moment and breathing helps you relax. Overthinking often comes from stress and lack of relaxation, which is exactly what you need to combat with the help of meditation techniques.
• Each time a situation comes up and you start thinking of all the things that could go wrong, switch and start thinking of all the things that could go right. That is not being in denial, but rather that is a healthy dose of positivity we all need. A little bit of self-pep talk is a part of loving yourself. Treat yourself with kindness, like you would treat someone you love.
• If your overthinking starts in moments you’re free and don’t have anything to do, get something to do. This doesn’t mean that you have to keep yourself busy all the time, because then that would mean that you have to stay distracted to avoid overthinking and that is unhealthy. Rather, find a hobby that relaxes you. Or watch a TV show, listen to a song, or just spend time with the people who matter. That can help you relax and stay busy, both at the same time.
• Write your thoughts down. You don’t have to be a writer for this, but you just need to vent and express. You can even rent to someone you’re comfortable with and if they’re willing to listen. The purpose is to get it out of you. Thoughts can turn to poison if they’re not dealt with and allowed to fester. 
• Learn the skill of letting go. You must realize that everything is not in your control. What is, you must change. What is not, you must learn to let go because worrying about it will not do you any good. This is easier than said and something that will come to you after years of doing it, but you must persist. One way to do this is by asking yourself, ‘will this matter in the next 5 years?’ if the answer is no, you shouldn’t give an ounce of your thought to it. if it does, then it is worth thinking about in the present moment.
