Ask anyone stuck on a big goal what needs to happen and they'll describe it exactly. They just haven't done the first thing.
The first thing is usually tiny and slightly embarrassing — an email to someone who might not reply, a form, a question that reveals you don't know something.
Start there rather than at the impressive part. Sequence is the skill people mistake for talent. Capability was never the bottleneck; what's missing is a decision about what comes first, and when.
