"Man's happiness in life is the result of man's own effort ... "
I believe that happiness is a matter of attitude. Happiness is the outcome of one's own thoughts and self-discipline. Being happy can depend on how you perceive life. If you gather enough positive thoughts, then chances are you will attract positive energy.
When you wake up in the morning, try thinking of the good things that will come your way. Set aside your problems and worries for a while and aim at fulfilling a positive start. I know that problems cannot simply be dismissed nor does it easily go away. But when it's the first thing that you ponder when you greet the morning, then you will just be burdened with a heavy heart. Try to face each morning with a light heart and see what happens. A smile can radiate positive energy. It wouldn't hurt to try.
So the next time you wake up, think of happy thoughts and put a smile on your face.
Have a wonderful morning.
