Don't you think that we are all one?

I think that there is no right or wrong since all human beings change over time dozens of times. I may become where you are (your stage) and you may be on someone else’s. I thought differently about various subjects at different times in my life and believed them to be ‘true’. But now I realized that I may very well change and think differently in the future too. I also feel connected to all human beings because of that. When I am talking to someone I don’t bluntly judge them because I think maybe they’ve been where I am mentally once and maybe I will be them. Am I making any sense? I would love some insight on this… Do you agree with me? We are all one basically.
