Keeping to be Silent

The inspiration.. 
If you're not sure of what to say, just keep silent. let them judge of something they really don't  know.

Quote of the day.. 
Better to remain silent and be thought a fool than to speak out and remove all doubt.

--Abraham Lincoln

 
Other idea... 

It is much better to be silent to keep other have the doubt, than speaking aloud and letting them know how little you've got.

Firming question..
Can you make yourself silent and sustain it?
