This is the most important of all the external conditions that can improve your happiness quotient. 

Often our deepest sources of unhappiness are found in poor relationships with others. A colleague at work who bullies or dismisses us creates untold wretchedness.

 A cruelly conflictual relationship with a partner or lover leaves us feeling betrayed and abandoned.

 A relationship with our parents or children which is not based on compassionate, unconditional regard creates isolation and misery.

 We never fully adapt to hostile relationships, they invidiously contaminate our wellbeing, squatting inside our minds as unresolved, destructive ruminations.

 When faced with such relationships, the most positive thing we can do is to either mend the relationship by confronting what is going wrong or learn to move on.
