I trade only for my own account so I think that's important. What I write in my newsletter, is what I am doing. I am up 5 percent up for the year. Do I get things wrong ? Yes absolutely.
The important thing to do is, not to stay wrong. And I try not to stay wrong for very long periods of time. The only thing that will take you out of this business is getting something wrong and adding to it, doing more of which is wrong. I have a very simple idiom, lets do more of what has been working and less of what has not. If you do that in life you will succeed, if you do that in investing, you will succeed.
