Problem is after experiencing the past we want to change our future by neglecting the reality of present we are making illusionsary world of future. Which isn't there actually. Because in the past we don't wanna live with some people but we lived with them intentionally or unintentionally. And we want to live with some people but unable to lived with them. In present we are doing the same. So In any phase of life don't neglect the reality.
