Typing analysis (of words) for Text Expansion

Hi MPUers, I was hoping to figure out a way to analyze what I type on my mac (over the last weeks) so I can figure out which words are the ones I type the most and can make text expansion for them. How can I accomplish this? Anybody tried this or any app that can help me to do this?

I don’t think that this is what you want to hear, but if you install textexpander it’ll make suggestions for you.
