You don't need to know them all!

In a pastry shop, each person has their role. One works the dough, another decorates, someone else sells. The magic happens because each role supports the others. They don't all need to know every step - it's about expertise, not everythingness.

For developers, the field pulls us in many directions. There's coding, sure, but also marketing, user funnels, traffic analysis, design principles, architectures, DevOps, you name it. And while there's this myth that a "great" engineer knows it all, the truth is simpler: you need to know one thing deeply and know it well. Excellence doesn't come from trying to do it all; it's about mastering your core skills and knowing when to collaborate.

A good developer writes solid code. A great one knows there's always someone in the team with the answer they don't have. You don't have to be great at everything.

But being great at something? That's where the difference lies.
