Apparently, if you forcibly smile, you'll feel happier.

Does this mean, we can see the world in different shades of colour to fit our moods?

More often than not, things seem black and white. 

Things go wrong, plans don't work out and the list goes on.

Try to change the color, the palette of your world. No more black and whites (except for upcoming photos) and paint the world to the colour you want.
