Check this chetan bhagat's inaguaral speech in symbiosis BBA program (http://groups.google.com/group/aiii/browse_thread/thread/1a62efc78041c55c?fwc=1) where he said
"We are like a pre-paid card with limited validity. If we are lucky, we may last another 50 years. And 50 years is just 2,500 weekends. Do we really need to get so worked up? It's ok, bunk a few classes, goof up a few interviews, fall in love. We are people, not programmed devices. "
I think he is very true, whats the big deal if you bunk few classes, goof up some interviews (but not all :P then u will be in trouble for sure). We should definitely have fun in life... its no point taking life so seriously since no one gets out of it alive. So as he told... fall in love.. do some adventure activities, travel a lot, learn all you like, nothign is wrong in this world.. do something new... try everything in life n enjoy!
