In my trading I had several great run ups when I more than doubled my account in a few months only to give it back in the next month or two. I was smart enough to stop at my initial capital and not blow the account, but giving back profits was damn painful. The reason was always position size. One example: I got from 100k to 270k (South African Rand) in about four months. I traded from 3 to 10 contracts using fixed ratio and the volatility expansion system by Larry Williams. The system has been described many times: entry = today's open plus yesterday's range times N. Vice versa for shorts. In retrospect, this system is quite cyclical. So I got to 10 contracts and made a "smart" decision: I am now going to trade in the multiples of 10 contracts using the same Delta. Then, after a loss, I stayed with the same size - what's better way to make the losses back, isn't it? After more losses still the same, overinflated size. When the smoke settled and I calculated what my account would be if I had the discipline to stick with the position size template. It turned out that my account would be about 25% down. Poor risk management got me back to the starting line.
