When I'm upset or down, I always use a little imagination...
To daydream my worries or sadness away!! ;)
Actually, I just stare at lovely sceneries and wish I was somewhere else. As if I can run away from all these worldly nonsense and rat-race...
Basically, I have this little mantra. I say "I wish I was a beautiful butterfly and then I can fly up up and away!" Sigh, too much of Disney and Pixar movies.
I caught that phrase from Bug's Life when the fat caterpillar wished he had wings to fly. That scene is the best. When he finally emerges from his cocoon, he has this cute little wings which obviously cannot sustain his weight to fly! But no harm, dreaming! :)
