Refuse to be unhappy.
All is just fine. Mind says.. how come everything is fine?
We got what we wanted. Mind says.. only that much? Want different variety.. so on..
You made a mistake.. mind will make you feel guilty.
Let anything happen. Let mind say anything. Just be happy. It is fine. It is ok. Enjoy life. Be happy every moment. Resolve to be joyful.
Keep Smiling not because of something.. but inspite of everything.
