Been trading for over 20 years. Like others that have been involved for this long, I have seen things change drastically and quickly. Any investor that says that they don't need to learn new things, they just stick to what they know, is not in touch with market reality. These markets change by the millisecond, and the best of the best can get caught. I have been mostly sticking to options and futures trading, because that it where the real fun is. By the way, if your not having fun and loving what you do, then maybe you should look for something else to do. That is not to say that we don't have our bad days, we all are human, but we should have more good days than bad. If not, then we need to change our approach.
