Easily distracted

Why is it that before I can start doing anything on my computer be it write, edit or anything not connected with writing (I mean literally anything) I check my email. Maybe it's because I'm hoping that there's going to be the email I'm waiting for to be there. From next week I'm going to try and get into the habit of doing what I switched the computer on for in the first place before I check messages. Maybe that way I'll do more work and less chatting/surfing/all the other distractions the internet offers because God knows I take precious little distracting. I don't know how well I'll manage because that email might be there but I'll give it a go.
