Hey there! Yes you! with the moody demeanour, why are you sad? Why are you laid back? Why are you always downtrodden?
There is a lot of sadness already in the world. We look to the left we see children crying, we look to the right we see mother's lamenting and fathers in deep thoughts on what next to do to better their lives.
We spend a lot of time worrying and creating personal problems even in a world full of chaos and problems. As one writer perfectly put it "we find a way to create a problem for every solution".
Happiness like sadness is also a personal choice, no matter the situation, been cheerful is halfway the solution. Try to be so positive that it influences persons around you, it reflects in your every being and most of all it lights up your life.
No one is responsible for your own happiness, only you.
