Unfortunately, options are the king of all financial products for the "Ah-ha" moment. No matter how well you think you understand things, until you see it, you don't.
If I had to pick the one thing that advanced my understanding more than anything else... I would ask my mentor questions almost every day, and he would respond every time with "go home, figure it out, and tell me the answer tomorrow." Every question led to another question, and every time I was met with the same response.
A year or so later, he left for another firm and was now trading against me in the same pit, when he confided in me that he never knew the answers to most of my questions, and thanked me for how much I taught him about options.
No one's going to teach you what you need to know, you will learn a lot more punching your way through your questions, and even if I somehow melded every piece of knowledge I have about trading to you, there is no guarantee you will perform positively.
Futures... up, down, right, wrong... not much more to it than that, until you get into time spreads.
