Being on Time: Overrated?

I've always had a problem when it comes to being on time. Best laid plans and all that, I still always seem to run at least 10 minutes late - for just about everything, and that includes personal things that actually matter to me.

For some reason, I feel like everyone (at least in my immediate circles) cares about being on time, as if it is a badge of honor. I think they're right, but I've still had a problem changing this bad habit. And here's what I'm thinking, I'm usually late because I'm trying to get "it all done." I'm usually not late because I'm sitting around twiddling my thumbs. I'm late because I had 46 more emails to respond to, a client that needed to talk to me NOW, packing that had to be done for an overseas trip, food that needed to be prepped for a dinner party that night and shoes that needed to be picked up at the repair shop. Honestly, I could be on time all the time if I cut down on something else. So being late in my case is a true time management issue, but that's what we're all trying to do these days, manage our time, aren't we? So, why is everyone better at it than me? And does it REALLY matter? 

I wish I was better at it - being on time. I don't want to be late. I really don't. I'm going to work on it,  just like everything else in my life. Wish there was more time!
