You are unhappy because you are not thankful to God what he has given to you without asking to him. You roll your eyes, you will find a good number of people around you who are either physically weaker than you or financially weaker than you or less intelligent than you. Have you ever thank God for making you healthier, financially stronger and more intelligent than many of the fellows surrounding you? If you do that, you will always be happy, otherwise not. To be happy or not to be, it is in your hand. Take your decision today and start smiling right now!
