Megastar Amitabh Bachchan, 74, feels there is so much to do, but not enough time.

The star has been in the film industry for almost five decades and has been entertaining movie buffs with his films like "Zanjeer", "Abhimaan", "Deewaar", "Sholay", "Don", "Shahenshah", "Paa" and "Piku".

On his blog, he wrote on Thursday: "...why is it that now one feels that there is a paucity of time to do much, when indeed there is much to do now? Why is it that when there is much to be done that doing that takes a million moons, knowing well enough that if not now then when... "

"To say to start small and build later progressively, leaves us in doubt. Others have more time than us. We think for the morning. Others think of the mornings of the future and this truth makes for indecisive thinking on many spheres."

He also wrote that people spend time in watching and involving their visions on today's creativity.

"We envy that it was not present in our time. We picture ourselves in them then and in them now," he said.

Big B believes that nostalgia is good, "but not when it does not compromise with us".

"I would wish to... but then time would have to wait. And time will not, neither will nostalgia," he said.
