Take a nice vacation first of all, to reward yourself for earning your success.
Learn investing from people who have been doing it a while, especially ones that have been successful. Educate yourself online. Investopedia is a good place to start for beginners to get the basics of investing. Maybe even start day trading. Start small (stocks no more than $5/share) and get good at it before putting real amounts of your money at risk. Set a budget of what you would be ok losing if that were to happen, as you learn the ropes on a small scale. Just like going to a casino, budget for loss, hope and try to do well.
