People are not focusing on you and what you did on March 12th, 2018. Why? Because they are focusing on themselves and what they did on August 28th, 2020.
When your brain recalls moments from your past, or even the mishaps you recently made... well, no one is actually thinking about it.
The spotlight effect describes the fact that people believe that they or their actions are noticed more than they are in reality.
They are on stage with the spotlight on them.
We are all in the centre of our own world, and so, we all believe that the spotlight is on us, our actions, our flaws and our mistakes.
In reality, because we are all under this effect, it is only you that is ruminating over these thoughts and actions.
This is not to say we don't care about the world around us and other people's actions.
We just show a natural bias towards ourselves.
Coming to terms with this fact has brought me a great deal of ease when these situations arise - and I hope it might put things into perspective for you too!
