I tried trading from 1993 to 1995. I made a little money, but not enough to justify the frustration. It cost $30 to $100 a trade then, even with "discount" Charles Schwab, and it just wasn't practical with the money I had.
So in 1996 I put it in funds, and left it alone.
In 1997, the asian currency scare spooked me. I moved everything into bonds.
In 1999, with interest rates dropping, I sold the bonds for a profit, and used that as a down payment on a house.
In 2002, with I decided to take advantage of the real estate bubble, and cashed out of the house.
I started trading again a few months ago.
NOT trading for several years, and completely avoiding the internet mania, probably is responsible for preserving my capital much better than for many people who got caught up in it.
