If anybody tells you from inside that you have doubts, you say no . You must find time for it, and it will be all right in due course. If you persist in It, It will come to you. The secret of success is that you can get anything you want, provided you want only that thing. But if you want two things, then you will get neither this nor that.
Nobody can live like that, with only one thing.
There is also another thing, second thing, third thing, etc. But there is one thing, by getting which, you will get other things, also. So, you may say there are no drops in the ocean, yet you can say it is made up of drops. Both notions are correct. Actually, the drops in the ocean are only conceptual.
