Not that long ago someone told me about the positivity challenge. The point of it is to only have positive thoughts for an entire week. As soon as you start having any negative feelings or thoughts, you will either have to twist them into something positive or try to think of something else instead.
It sounded great and very promising: no more stress or anxiety, no more sadness, no more anger, only positivity. So I decided to give it a try. In fact, I tried it multiple times and it never worked for me. Trying to turn negative emotions around brought even more negativity in my life.
