I get what you're saying, but disagree. "Chef" kind of already means "professional cook" and "contractor" is kind of a legal term when it comes to construction, but if you draw in your notebook, you're definitely an artist. You may not be a good one! And you may not be professional. But who cares?
This is why we have qualifiers: "I'm an award-winning chef." "I'm a world-renowned artist." "I'm a professional designer." Of course you shouldn't go around calling yourself a doctor just because you once successfully took an aspirin to get rid of a headache. But when it comes to creative endeavors, I think more people should be proud of the creative act itself, even if it's not great on some objective scale. And I wish more people would attempt casual acts of creativity. And I think those who do deserve to wear the title of "artist, "designer," "cook," "painter," "writer," or whatever.
I too wish people would attempt casual acts of creativity and be more proud of the creative act itself. But they can do that without being "a(n) ______" after their first and possibly only attempt.
I'm not saying that there needs to be an objective standard of quality or number of hours put into an endeavour - even a terrible fisherman is still a fisherman if s/he practices it. But I wouldn't go fishing once and declare myself a fisherman if I had no followup experience. If I were to say "I'm a fisherman" in conversation, I think it would demonstrate a lack of common understanding about what that sentence implies, or duplicity at worst (trying to curry favour from a fishing enthusiast boss, for example).
I get what you're saying and I know you're coming from a positive place. I just think that it runs counter to the common interpretation of "a(n) _____", and I'd rather preserve that interpretation because it's useful.
