The first thing to learn in any gambling game is when not to play/fold your hand. I suggest you go with a diversified portfolio rather than try to 'make money'.

If you have less than $500,000 I suggest you spend your time on ways to increase your earned income. For example instead of reading investment books, read all material related to whatever field your are working in.
1) learn who the most important people in your field are.
2) learn who can give you a promotion (hint it is not likely to be your boss).
