You might market yourself as your niche, it might be many people’s perspective of you, it might be how you earn your living, but it’s only a story.
It’s not you.
There will be a time and a place for this story.
Going to a convention on your niche is a great time and place to put that story at the forefront.
A job interview is a great time to emphasise your niche.
Your Twitter bio might be a good place to talk about your niche.
But that doesn’t turn you into your niche.
You’re still allowed to be whoever else you want to be and do whatever else you want to do.
Focusing on your niche will allow you to be more effective in that area, but you don’t have to be afraid of being tied down to it forever. You’re still human.
