You are so lucky to have enough time to enjoy nature of nature... I hardly slept last night due to work, peace of mind drowned in maximizing earning capacity, with only signs left for dreams to spent sometime with the real brown earth, fragnance of breeze, open skies, and spinkling water.....

so, if you hardly slept, how did you not have the time to enjoy nature?  Perhaps sitting outside for a while, regardless of time of day, would have helped you to relax so you could sleep better...

I could not have time because my assignments, computer, classes, library, hostel rooms are indoors. Infact campus itself is beautiful although in mid of city.... but today I went and played badminton for 2 hours and it feels great....

Oh, I guess when you said that you hardly slept, I invisioned someone tossing and turning in their sleep/suffering from insomnia.
pardon me.
