Re: 10 second questions
Hi ganesh;
You know centuries ago when I was supposed be learning this. I skipped over it. Too easy, I said. Didn't memorize any formulas or even take adequate notes. You know the kind you can read later. So I am getting a good workout because I am fixing my notes.
Someone told me that the real difference between Albert Einstein and the rest was his notes. He said Al kept the best notes he ever saw. I don't know if you will be great if you keep great notes but I do know you will have a hard time if you don't.
