Do one thing this month that makes your hands shake a little. Ambition grows in those moments.

Nerve works like a muscle, in that it responds to load. Staying inside what feels safe keeps the boundary exactly where it is, and every time you do something slightly frightening and survive it, the boundary moves. The shaking is not a warning. It is the sensation of operating at the current edge of what you can do.

Choose something specific and modest: send the message, ask the question in front of people, sign up for the thing you are not quite ready for. Keep it small enough to recover from easily. Do one a month and the old edge will look tiny.
