"go around twice if you are happy"

go around twice if you are happy -- not that easy to understand what it exactly means. sometime back my friend has given me the url of this "go around twice if you are happy", from ever burning video sharing site, youtube. at the first instance, i too could not quite get what it means. it was kind of strange and that to a video with that....i thought it is some animal video , meaning some home made video that we normally get to see on net. but this is not that..i donno much about this video - where it has been shot, who and how popular this video as such..but it has message actually..the video goes like this...hey..this video is well corroborated with background score...it is soothing to tired ears...the video start with something revolving around a space...guided by some laws of the forces. then they take us to a road where a stream of vehicles keep coming and going and on the roadsides we get to see plethora of sign boards, displaying some really funny and at times..make more sense than anything in this world....for sample a board reads..."beep your horn if your in love" another reads..."turn on your hazzards if would rather be in bed" and after many such boards ..at one point we reach a 4 way or 5 way junction where a board displays..."go around twice if you are happy"....quite catchy..is it not? what exactly it means is ..go around that circular junction if you are feeling happy..just about something or anything for that matter...and one interesting thing is... many vehicles do go around twice and some even more than 2 times i suppose...but somebody like me would have taken some n number of turns even when i am not happy...why?? just for the fun part of it....if we are not happy..we should do something which gives us happy...and these guys - whoever made this video have in fact made a big difference in many peoples life....it is not enough..if just we are happy....that's not going to change anything in this world..oh! yeah right question why do WE NEED to change this world? ..ya i am asking it again..why should we change this world?? it is not our business...right? no, not quite to the mark..i do not see even a atom of reason in this point.....just try sharing your happiness with the people around you...it can only increase in leaps and bounds it is jsut like a big bang whose horizons boundless...it will become a avalanche of sorts...and take everyone around you for a ride...n that is what the ultimate joy....why i am saying this..because not the entire world recognize this simple fact of the life...self centric attitude...aaah..so pathetic and mean...it is not good for this world...oh oh..toomuch gyan i think....who is going to listen to all this anyway..if i really believe in this...let me follow it..stop preacing and start following...tata
