One's perspectives are only limited if one has not considered the breadth of alternatives. Having reviewed the alternatives does not thereafter require accepting them all as equally valid.
That certainly shows how set in your ways you are. After all, you have already "reviewed the alternatives".
My hope is that if, when I get OLD LIKE YOU, I still will be open to others perspectives, NOT BITTER AND ANGRY ABOUT THINGS THAT HAVE CHANGED.
From 'The Art Of Peace':
Life is growth. If we stop growing, technically and spiritually, we are as good as dead
