greens...

have always noticed the different shades of green on the trees and plants.

Had once attended a talk in school when we were in the 10th std. it being our board exam year, the talk was about how we should keep a schedule and study regularly.dont rememeber most of the tips and tricks that were told to us, but for this one which is still fresh.
the lady giving the talk said, in the morning when you wake up to study, and are struggling to keep your eyes open, go out into your balcony and stare into the trees/plants:The green color has a quality that makes you feel fresh and energetic.
dont know how true it was and how much it actually works.
but i know that its the greens,the foliage, the views from hill tops showing vast forests that give me this strange feeling which definately fits into the 'fresh/energetic/positive' category. :)
