In thinking about this diary, I have become cognizant of my own investing styles and techniques. Great! This is a positive thing for me. I think too many people take a pell-mell approach to investing. One day they like gold; the next day they like equities. They have no conviction in what they bought or a sound exit strategy. I have made this mistake myself. I still do.

1) We need an investing strategy
2) We need an exit strategy
3) We need investments
