You create your own reality by giving meaning to things you see, hear, feel, think and experience. Events you observe are being processed by your brain, which turns it into a perception. This perception influences your mood, and this mood affects your actions. Events in itself have no meaning.
Let’s look at an example. When you grab a cup from the cupboard and everything else comes tumbling down with it, than this event is what it is. You’re grabbing something and stuff falls down. Nothing more, nothing less. Still, the way you react to that situation might be totally different than the way your partner reacts.
Some goes for creepy crawlies, small animals with a tiny body and six legs. Nothing more, nothing less. They might not scare you, while other people totally freak out when spotting a bug.
This shows it’s not the situation or the event that determines your reaction and action, but it’s the meaning you assign to it, your own perception.
Your thinking pattern
From a young age, you were taught to think a certain way. You were taught by your parents, teachers and your peers. As a child, you were taught morals, values, principles, rules and manners, and you absorbed it all eagerly. This is how your thinking pattern was shaped.
Your thinking pattern tells you how to think about yourself, about others and about life. You could almost say that you’ve been programmed to think a certain way. It’s no coincidence that you often react the same way to similar situations, even though you’d like to react differently (maybe not as insecure, angry, scared or annoyed). This is because your brain assigns current events to similar past ones. Your brain then remembers and recalls the mood of that past event. And this mood affects your actions.
