I am so happy these days! I would say happiness stands in the way of reflection and deep thinking, but it brings positive thoughts, smiles and good intention to the surface. So I am happy about being happy. Even the sun is shining today!
When you feel down, you question everything, you feel like floating in uncertainty, not seeing the way out. Once you're happy you ask why would you be looking for a way out...a way out from where? To where?
And ulitmately, I think feeling happy is sometimes a matter of choice to ALWAYS LOOK AT THE BRIGHT SIDE OF LIFE :-)
Cheers!
