Stop trying to find happiness and just be happy. Simple!
If you think about it, all your desires in life (e.g. new car, more money, healthy body) all aspire to one thing - to make you happy. All too often we let our circumstances control how we feel. Instead, try letting how you feel control your circumstances, and you CAN control how you feel. Just smile or visualize yourself achieving your hearts desires and you do not need material things in order to gain your ultimate desire - HAPPINESS
