Trader or Investor?

I thought this was posted before, but I cannot find it.

“I was having a discussion with a friend of mine who calls himself an 'Investor'. So, I asked him, "What's the difference between a Trader and an Investor?"
He replied, "I don't know, let me think about it for a while . . .”

 

an investor is one who loses his a$$ by night,

a trader.. by day.
