I agree with you to a certain point. It is true: mind over matter. But reality is a objective thing and when we talk about it we often say "my reality vs your reality" and what we mean by that is "my perception vs your perception" but what lies within those words is just "my distortion of the reality vs your distortion of the reality". Reality is objective, yes. But I think the thing that you have figured out is not, that you changed YOUR reality by simply having another view on it, but rather that you changed reality ITSELF by having another view on it. If it just would've been "your" reality you've changed, you would't notice any difference, because reality is a structure that is created by every living being. So if you have changed your behaviour and how you see the things around you, most certainly other people will see you as well with different eyes and therefore you changed "their" reality or reality itself as well! Just my humble thoughts. Keep going brother. Find your way! Love from Berlin.
