Write down what you’d attempt if a year of failing cost nothing. Then find the smallest real version of it.

Most ambitions get filtered before you ever see them, cut down by an estimate of what failing would cost. Removing that cost for a moment lets you find out what you actually want, which is information you otherwise never get. Then the useful move is to shrink it rather than drop it, because there is almost always a version small enough to start now and real enough to teach you something.

Spend ten minutes writing the list honestly, with nothing ruled out for being unrealistic. Pick one and ask what its one-week version is. Do that before the month ends.
