I can never be safe; I always try and go against the grain. As soon as I accomplish one thing, I just set a higher goal. That's how I've gotten to where I am.
When stocks are attractive, you buy them. Sure, they can go lower. I've bought stocks at $12 that went to $2, but then they later went to $30. You just don't know when you can catch the bottom.
Stay hungry, stay foolish.
