I have consistently outperformed the market since 2007, when I started investing (I refer to the market as the DOW).
Just because the average salary in the United States is $57,000 (random-ish number) does not mean that's what I have to settle for because it's the average. If I put in the time, work smart, work hard, and keep learning, then the expectation is that I can beat the average income. Likewise, I can beat the average market by putting in more time, more effort, more learning, than the average investor.
I tried forex for 2 years, and did poorly, so I stopped, and learned my lesson.
I bet on Ford at 1.60. I bet on Tesla at 16, and 24. (not heavily mind you, just 2.5% of my portfolio). I research the companies, the management. I not only go to the annual report, but I also read books by the founders, read about their manufacturing (are they using lean like Toyota or lean like GE?). I went after Ford based on Mullally's performance at Boeing. I went after Boeing based on the 787's promises. (It's doing very well.) I read Deming.
I lost $900 in American Airlines, and $300 in Washington Mutual. I did lose $6K on a $10K mutual fund that went south in 2007-2008. It looked like it would recover, but then wasn't following the market up. I've made a lot less money with mutual funds that with stocks.
Granted, I've been riding a pretty nice wave since the drops of fall 2007 and mid 2008, but I don't blindly pick a stock and buy in. I'm very careful where I put the money, and will do 2-4 weeks of research on a single company.
I also research their competition, and business trends in general. This means I don't watch TV, don't watch sports, and will do one movie per month with my son. Instead, I read. A lot.
I do max my 401k because of company matching, but I'm not holding my breath on returns. There's an event horizon where it's better not to match and buy securities directly, because of the 1% or so fees. (You start out with twice as much, but you get less annual yield.) You don't pay taxes till you sell, and you can sell at a time of your choosing.
I don't day-trade, I don't even month-trade. I generally invest for 7-15 years.
Finally, I invest only my own money, and that is a very strong motivator for spending the time to do it right. (Small caps do slightly better than large caps--more risk, more return. Diversify.)
