Daily stock market swings

I am guilty of paying too much attention to the daily stock market swings. Every night I try to update my Quicken accounts. I do notice that I am a lot less enthusiastic about the daily updates on down market days. Experts say that you should not watch your accounts so closely and only update every month or so. I can’t seem to help myself though. I get a rush when I see that my investments have increased in value. Of course on down days I feel like I have been kicked in the gut.
