Subjective reality seems very challenging to hold as a belief system. I've been slowly making my way to this belief system, with occasional lapses where I forget and go back to objectivity. The whole issue is that other people in your reality consistently reinforce the objective model. But they're not really other people, they are all you and you are everything that exists in the present moment. The biggest shift has to be from ego-centeredness to awareness-centeredness. Maintaining that perspective is exhausting and challenging at the point I am at right now.
I just wish I knew someone who was as interested in this stuff as me. I used to know someone, but he is no longer on this plane of existence. I guess the next time there is an SRW (if there is), I'll have to go and see if it gives me the breakthrough I need to truly embrace this belief. It's just very hard to maintain it from my personal experience.
