If you're ever worried, do what I did: Make it a goal to take a picture every day of something you did. Could be as small as yardwork. Just try to make the picture interesting, even if you're not doing anything interesting. If you can't get an interesting picture doing what you're doing, try and carve out 30 minutes to do something fancy.
Lots of it is also a matter of difference of opinion. I used to read some developers' personal blogs and every time they posted a photo, I'd feel some weird envy, even when it was stupid photos. "Oh, man, he and a friend went to buy some milk! I hate that I'm inside living a boring life!" The difference between "Damn it, got to buy some groceries..." and "Voyage to the grocery store!" is more one of perspective than it's one of doing exotic things.
In some cases, I just like being part of the talk. Right now that's Hacker News and Something Awful, because Reddit people frustrate me and the idea of losing days to Metafilter scares me. I'm also a little obsessive re:design. I like clicking every link on every web site to see where it takes me.
In a lot of cases, I like going through a site's history, reading up on its culture. I've spent a day or two going through the YTMND wiki, for instance, and right now I'm looking through the Let's Play Archive, which has quite a lot of fascinating stuff. My favorite moment there so far is http://lparchive.org/LetsPlay/OregonTrail/Update%2021/index...., an Oregon Trail run where, to decide a single action at a river, people wrote a hundred or so poems stating their opinions.
