“You are unhappy because you have chosen a wrong attitude towards life. You can be happy if you choose a right attitude. Buddha pays so much attention to ‘right attitude.’ He makes it a base, a foundation — right attitude. What is right attitude? What is the criterion? To me this is the criterion: the attitude that makes you happy is the right attitude, and there is no objective criterion. The attitude that makes you unhappy and miserable is the wrong attitude. The criterion is subjective; your happiness is the criterion.”
~ Osho
