To become happy, you have to come to integrity of yourself, to come to integrity of yourself, you have to accept yourself, to accept yourself, you have to change, and to change, you have to want to change. Why will a person want to change? Something bad has to happen to a person, so that he or she will want to change, otherwise, why will a person change out of nothing? Why will a person want to change anything, if everything is already fine? 

Therefore, bad things happen for our own good.
