A title cannot contain a whole person
The words beneath your name may explain what you do, but they cannot hold everything you notice, enjoy, make or hope to become. Leave yourself enough room to be the person who loves old maps or cooks an excellent breakfast, even when none of it belongs on your introduction.

Beyond the introduction
Introductions compress people for practical reasons. A job title helps someone understand why you are at a meeting. It says very little about what occupies your attention on a free afternoon.
A useful description is still a partial description. Trouble begins when you expect it to include every part of you, or dismiss interests because they do not strengthen that description.
You can enjoy drawing street corners without becoming an illustrator. You can be interested in train stations without making that interest part of your professional identity.
Try finishing a sentence that would rarely appear in a formal introduction: I am also someone who enjoys...
There is no need to make the answer impressive or useful. It can be as particular as arranging fruit in a bowl or recognizing the sound of an approaching train.
