Wise men

Wise men speak 
because they have something to say
Fools because they have to say something

quote by Plato

Wisdom

Knowledge is knowing a tomato is a fruit

Wisdom is not putting it in a fruit salad

quote by Miles Kington

Knowing everything

Those people who think they know everything 
are a great annoyance to those of us who do. 

Quote by Isaac Asimov

Sit and think - Warren buffet

I insist on a lot of time being spent, almost every day, to just sit and think. That is very uncommon in American business. I read and think. So I do more reading and thinking, and make less impulse decisions than most people in business. 
I do it because I like this kind of life.

quote by Warren Buffet

Silence

It is better to remain silent and be thought a fool
than to open one's mouth and remove all doubt.


Quote by Abraham Lincoln

Nothing in life is to be feared

Nothing in life is to be feared, it is only to be understood.
Now is the time to understand more, so that we may fear less.

quote by Marie Curie

18

Common sense is the collection of prejudices acquired by age eighteen.
