The project that scares you a little is the one that’ll teach you the most.

Mild fear usually means a stretch rather than a danger: you are being asked to do something you have not proven you can. Projects inside your range confirm what you already know and leave you where you were. The scary one has an unknown in it, and resolving that unknown is the learning. The nerves are measuring the gap, which is useful information.

Choose the version with one thing in it you do not yet know how to do. Name that thing out loud so it stops being a vague dread. Build in time for it to go wrong once, because that is the part you came for.
