I used to be online all day long. I had a laptop on the kitchen table always on and connected throughout the day. Now I restrict myself to getting online only after the children are in bed and my chores are done. I may not even have 30 minutes online time, and I realize that that is okay.
I used to be quite addicted to being online. I could literally feel the rush when I turned on my computer. So strange.
I made a conscience decision to limit my time online, and it was difficult at first. But I think it is better for me. Too much information all the time is very tiring.
Nowadays, I get online, do what I need to do (mainly email), and I get offline. Except tonight. I should have been offline ten minutes ago, and I came to post on my blog instead. :)
