One of the things I've really come to appreciate about being a student again is that my access to email is extremely limited. I'm in class most of the day, so it's not unusual for me to check my email account once in the morning and once towards the end of the day... and in neither case do I spend more than 20 minutes at a time.
Even better, I can't get to my gmail at all during the day - and when I'm home, I want to be home and engaged with my family, so I don't spend much time reading/writing email then either.
Now, I'm not getting a lot of email these days - no status reports, requests for information, etc. Most of my official communication is via class presentations, etc. But once I'm back in a regular job, I am seriously going to consider limiting email to certain times of the day. I've heard it's a good way to manage your time and not turn your day into a series of short (or long?) interruptions.
At any rate, I like it.
