The only perspective we will ever have is our own. Even if we do the important work to put ourselves in the shoes of others and broaden our own perspective, we will still only see through our interpretation of what another's perspective is.
There is nothing to do about this except fully embrace it. When we can remember that we each have our own perspective, we can realize how valuable that is. It is from each of us having our own perspective that others can help us become aware of what we would not be able to see from our point of view. We can understand that our way of seeing things matters, and that sharing from where we stand can make a difference. We can also learn not to take things personally as everyone is always looking at things from a different place than we are, so we can't say what is right or wrong about what they see. We can only do our best to know that if we were standing where they are, we would see what they see.
Perspective is a key function of individuality. There is much to learn from honoring our own perspectives and honoring the perspectives of others. Denial of another's perspective keeps us stuck. Honoring our individuality is the first step in working together.
