It happens, but you learn from it. Now, you know what to look for.

For example so many investors/traders believe just buying a stock they will become rich. That is very far from the truth. It takes time to practice and learn with a little luck. From my perspective running this site I've learned a lot in the past 5 years. If I had to restart everything today I would be able to cut over 4 and a half years off of that because now I know exactly what I need to do.
