You make something you like. A friend sees it and says, “You could sell these.”
It is meant as a compliment. You may even be pleased. But suddenly the thing you were enjoying has another possible future: orders, a website, packaging, a reason to post about it.
There is nothing wrong with that future. Many worthwhile businesses begin with something a person loves doing.
You are also allowed to keep making the thing without becoming responsible for supplying it.
The same applies to an interest that never produces an object. You can learn about architecture without changing careers. Take photographs without building a following. Become absorbed in a subject that will never appear in your professional biography.
It can be surprisingly difficult to leave an interest at that scale, particularly if you are accustomed to spotting possibilities and making things happen.
You see how it could grow. You know how you would improve it. You begin to imagine what it might become.
Before following that instinct, consider what you enjoy about the activity now.
Perhaps it is private. Perhaps there are no deadlines. Perhaps you can stop halfway through, make something badly, or change your mind without disappointing anyone.
Those conditions may be part of its appeal.
You can decide later whether you want to take it further. For now, you might prefer to spend an hour doing it and leave the question of potential alone.
Enjoyment is already something to have come of it.
