π Mind Plane
Can we solve a problem? If not, then why stress about it? If yes then why stress about it? Why should we not be optimistic about everything?

You live in Your Reality! While it is true there is an external, physical reality, we all live in our reality. How we perceive events, how we interpret everything, how we see the world is a result of our internal programing/Mind/Matrix. This is why in the same circumstances somebody can see things in a great perspective and somebody as very bad. But seeing is believing, so why not believe things are great? How would our life be, if for all the past events and problems that we solved, and we had a negative view, negative emotions and stress we had a positive relaxed, no stress view? The result is the same, things got fixed, but the experience is totally different.
