Is it even possible to expect nothing from others just to get not disappointed? But I do want to tell you this. It has played out well in life over the years. We really have unmet expectations that causes huge disappointments in our lives. "Expect nothing from anyone and you will never be disappointed" is thru. You know why? We do not know people's situation. Even family members. We really do not know the road that they are going thru. We do not know the whole story. We do not know their history. We do not know the whole perspective.
What we should do is be focusing on what we are responsible of doing - the things that we should be doing.
