Yes you are right. I still remember the day when I was about to

do the clicks on my computer to push in nearly half a million into SP 500, I was nervous.  I was afraid that tomorrow it would crash.  I clenched my teeth and did it.  It turned out to be OK and our net profit is more than $200,000 so far this year, but I was nervous.  You are right; it is a fight between fear and greed.
