It’s impossible to think two thoughts at the same time. Try it – it physically can’t be done.

Using this principle is a super-effective way to stop yourself from having your thoughts spiral out of control, say when you get in a bad mood and start ruminating, complaining and getting agitated.

It’s as easy as swapping a negative thought for a positive thought. If you feel fed up or upset for some reason, try replacing the originating negative thought for a new, uplifting thought.

Some positive replacement thoughts include things to which you are looking forward, like your next holiday, or even some fun activities you have planned over the weekend.

Harnessing this simple yet profound power to choose one thought over another is vital to helping regulate our mood and preserving our peace of mind.
