If you've tagged posts with a tag, you can pin that tag to your profile, which adds a link that only shows your posts with that tag.
This means you can tag all of your art "my art," letting visitors click it and see all of your art. Same goes for "my writing" for writing, "my commissions" for pieces you've commissioned, and so on.
This has one side effect that's very easy to overlook. Check out the contents of the following tags, which I found by just typing "my " into search and then looking at the results for each letter of the alphabet. You can bookmark these, find permutations of them, make more like them to fit what you want to post (and then pin to keep track of), or tag your own stuff with them to keep track, and to help the tag grow healthy and strong.
