Exchange Traded Funds (ETF)

After reading an article a few weeks back about starting to invest with as little as a $100 I started to give some thought to Exchange Traded Funds (ETF). I hit up one of my buddies who is a financial planner and asked for a few ETFs to consider. He came back with a few suggestions and I have been watching them rather closely. The problem I have with ETFs is that they are so boring! I only own a few positions and all of them are high risk - high return stocks. I enjoy watching throughout the week as my stocks go up 10% in a day then drop 12% the next day just to go back up 5% the following. It is a small jolt of excitement in on an otherwise mundane work week. The ETF's just kind of sit there and only move based on credible market elements. I prefer the rollercoaster ride of the news driven, yet to turn a profit, gambler stocks. I am fully aware that this is not a strong basis for anyone's portfolio but I figure that is what my 403B is for, this is to try and score the big one. I have yet to hit anything big that sustained it's growth but I figure by the laws of probability I should hit at least hit one before I die. The laws do say that, right?
