I thought this thread may be a question for me:)
Yep, round numbers are fun, even the market thinks so!
Glad I don't own individual stocks as I would probably check them every hour or so! I went several years, only checking once or twice a month or so when I made purchases. Never used to check the 401(k) much at all because it was on auto. But now I check almost every day as I am coming down to the wire. It's a lot of fun when most of the news is good and you are advancing towards the goal almost every day! When things turn south I tend not to check as much, only when I am buying.
