finding THE RIGHT BUSINESS

When I see around I see many succesfull people around having made their marks in various fields. One always feels that to start something and make it go as per expectations is no childs play. Having said that when I again look around for a second oppurtunity I always feel thats it one cannot have more things than this in the world, all needed inventions are done and whatever services had to be started are done so........ WAt To DO now ???? Wat business to get into ??? wat to start that really clicks ...??? This questions takes us to the brim and makes us to think something out of the blue and start something that has not been heard of so far.. the concept should be fresh and it should be new.. people should feel interested and they should continue to do so till the thing is supported by me .... always I should be on my toes to start that and make sure I am as fresh as vigourous as I had been on the first day .. the zeal in me should not die down and I should be up and running ... facing the world....and bringing the very best of me out..
