I can make a logo that looks decent. But when a client asks me for a whole identity, the fuller thing, how it feels, how it holds together across everything, I realize I don't actually know how to build that. I hand over a nice mark and quietly hope they don't notice how much is missing.
More people experience this than they realize.
You can make a logo but building a full brand identity eludes you.
If this sounds familiar, the Library can help you find the bigger picture.
