How to stop overthinking


Are you an overthinker?

Of course, we’re all thinking all the time – whether consciously or unconsciously. Our mind never really stops spitting out thoughts, therefore thinking itself is not the problem. Rather, it’s the kind of thoughts you’re engaging in and the amount of energy you’re giving to really unhelpful thoughts that will get you into trouble.

I’ve come to recognise a few common culprits that fall into the ‘overthinking’ category and cause you the most distress. Here I’ve listed my top three and given you some tips for how you might overcome them.


This is the very definition of overthinking. It essentially means to obsess over a problem and to keep thinking about it from every angle without doing anything productive to solve it. You know how they call cows ruminants because they keep regurgitating their stomach contents and chewing over it again? (I know.. gross!) Well that is essentially what we are doing when we ruminate. Chewing the same stuff over and over – but not the contents of our stomach, the contents of our minds.

This kind of unproductive, obsessive problem focus is a massive time-waster and strongly linked to increased rates of depression and anxiety. There are various ways to break the habit of rumination:

  • When you notice yourself going down that path, imagine a stop sign in your head and tell yourself STOP. Then immediately switch your thoughts to something more pleasant, more present focused or positive.
  • Give your mind a distraction. Call a friend, read a book, play music, start a new task. Find out what works for you to keep your mind from wandering back to the problem
  • Remind yourself that what you are doing is NOT problem solving and is in fact, likely making things worse. Don’t let yourself be fooled into believing this thinking is productive.

Second guessing

This is when you question everything you do and say, and every decision you make, never trusting yourself to get anything right. It could come up when you’re making decisions about what job to take or what outfit to wear. If it’s about things you’ve already done, you might rehash it wondering if you’ve said or done the right thing. Every little thing is subjected to your own harsh scrutiny, constantly wondering if you should have done something differently. Here’s what to do about it:

  • Practice being more comfortable with uncertainty. Second-guessing yourself is a type of anxiety caused by needing to be 100% sure you’ve done the right thing. Of course, nothing in life is 100% guaranteed (and even if something is right for a short time, things can change in an instant!) so learning to live in a world that is inherently uncertain is essential for your sanity.
  • Challenge your ideas about the importance of some of these decisions. Will it matter in a year? Does it matter to anyone else but you? Is this decision entirely irreversible such that you will live with devastating consequences for the rest of your natural born life? Probably not. So relax.

Mind reading

This is when you obsess over what other people might be thinking or will think about you. It has elements of rumination and a bit of second guessing which makes it doubly torturous. It is often highly self-critical thinking because you assume other people have negative thoughts about you or your decisions. Mind reading is one of the worst kinds of over-thinking because at the end of the day, it’s pure fantasy. Not only are you taking the worst, most judgmental thoughts about yourself but you’re attributing them to someone else without any way of checking the validity of your assumptions. Bad idea!

  • When you notice yourself fixating on what you think other people are thinking or guessing what other people’s objectives or motivations are, use all the skills I mentioned in Point 1 to stop and shift your attention.
  • Remind yourself that your mind’s inbuilt negativity bias means you will always assume the worst. This is part of your biological make-up but you are can take control of those thoughts.
  • If possible, simply let go of those thoughts. If not, try coming up with several more positive scenarios to replace your negative assumptions and remind yourself that since you’re only guessing anyway, the positive options are just as likely to be true.

Of course one of the best ways to manage all the unhelpful thinking traps we all fall into is by practicing mindfulness. When you can learn to watch your thoughts with curiosity (or even humour!) instead of being consumed by them, and you finally are able to stop believing all the terrible stories you’re telling yourself, you open up to a whole new way of living.

    […] By developing an increased capacity for mindfulness, you bring yourself into the present and realise what you’re doing. When you’re actually aware of what you’re doing, you realise you have a great number of other options available to you! You also learn to know what your triggers are for mindless, compulsive or emotional eating and you’re more able to catch yourself before you fall into those old bad habits. […]

    Hi Cass
    I’ve tried two email address but had not luck downloading the PDF, thus accessing the 3min meditation track.
    Thanks for helping <3

    I wrote the following comment on Youtube

    "Hi Cass,
    Thanks so much for this video.
    It took me over 15 years of therapy to get to this point where I can say " okay that's it ! these are my symptoms, and that's how I overcome them"
    I did try to look into "Indecisiveness and anxiety" in the past, with not much results on google.
    All these years of therapy I was told do mindfulness, but I wasn't convinced/motivated enough… but have a video like this that explains how mindfulness help specifically for this issue is a revelation changer"
