The line came from Warren Buffet, the billionaire investor:
Keep control of your time; and you can’t unless you do say “No” .Warren Buffett
“No” is a miracle word. It’s a word of freedom. It gives you time to do what is significant.
A lot of things are not worth your time. Those are the ones you should learn to shoot that miracle word against.
Saying “No” doesn’t mean you are lazy_ it rather means you don’t have time for every thing.
Successful men have time for only a fee things. And if you must be successful, that’s a habit you must cultivate.
Start saying “No” most of the times to some requests and you will see how helpful a word it is.
