Every one person has their own stories we can not underestimate any of the one because in this life everyone is facing problems in their own life either in some of the person the problem is small and in some of the its worst.
As I have told you we all have our own stories and our own good or bad past and how we are living it and how we are handling the situation is totally depends on you.
We all have faced so many problems in our life either in some of the cases we have faced the problems like a hell of ride some of them gave up and some of them stood against them and fought the situations like a ruler and a winner.
So if anyone is not sharing their stories with you its might be possible they have faced so worst problems in the past that's why they don't wanna share their past experiences with you as they are not comfortable to share with so for the same we don't pressurized them for this.
So live the life accordingly and enjoy your life.
