Use your free time to read and learn about the market, try to spend about a hour or two every day keeping up with market sentiment. Once you begin to understand market moves, dive into some (light) trend analysis. Trend Analysis feels like horoscopes at times but it gives you a sense of traditional market psychology which you can correlate to news, rumors, etc. It's pretty entertaining if you can devote your time to it but it usually becomes an all-consuming venture.
