When you doubt your skills, it's easy to think that adding more stuff, doing more things, proving more of your expertise is going to remove the doubt.
However, what that usually ends up doing is fueling the doubt. Because others who come across your work, while they might find it incredibly helpful and amazing, they might easily get overwhelmed by the stuff put on top.
You don't need more stuff.
You don't need to prove yourself and your skills.
You don't need to do it all.
Focus more on the ease, the flow, the space. And everyone else will feel safe to breathe and just be around you.
