Invest in adderall and see where that takes you. Joking.
In all seriousness, drop the desire to turn 100k into 1 mil in x amount of time. That will lead you into wreckless, speculative behavior. Trading is tempting for you because it offers instant feedback. With one or two successful trades, people tend to extrapolate their returns into future returns, believing that it's possible to repeat these trades over and over again. Odds are stacked against them. Don't fall victim to this thought pattern.
Smart investors invest where their odds are highest of winning. From what you've written, it sounds like that investment would be in yourself. What led you to this "blockbuster" year? Can you grow and expand upon the factors that led to such a successful year? I'm sure there's some opportunity. Do it.
