Solipsism is the philosophical idea that only one’s own mind is sure to exist. The term comes from Latin solus (alone) and ipse (self). Solipsism as an epistemological position holds that knowledge of anything outside one’s own mind is unsure. The external world and other minds cannot be known, and might not exist outside the mind.
This is what wikipedia tells about Solipsism. What you is is what you want to see. You are creating what’s around you, what you see, hear and feel. You are in control of everything around you. You are leading your own life to the target you want to lead your life.
Their are walls to climb over just to test you on your skills of strength to lead the life you want achieve only what you really want. Created by you; your mind.
