A person who is disturbed can-not be happy. For inner happiness one neds to get detached from desires and expectations. Persistent attachment to even one of the senses can be responsible for all unhappiness.
Lord Krishna first took Arjuna to his near and dears (Dronacharya and Bhishma Pitamaha) and not Duryodhana. He first developed attachment ( moha) in Arjuna and then taught him how to detach by narrating Bhagavad Gita.
Happiness also depends on your interpretations of your choices. Every action is due to your chosen actions based on your past experiences or your present choice to experiment. Only 10% of the actions are dependent on the circumstances where you cannot have control. If you have yourself chosen some actions, then why worry about their results.
