In order to attain the impossible, one must attempt the absurd.

Anything genuinely beyond current reach will look ridiculous while it is still only an intention. That is the ordinary cost of aiming past what has already been done: you have to be willing to be seen trying something with no track record and no guarantee. Reasonable goals are reasonable because somebody already proved them. The ones that move the line start out hard to tell apart from foolishness.

Name the thing you want that you have been keeping quiet because it sounds unserious. Take one visible step toward it this week, small enough to survive looking silly. Say it out loud to one person who will not laugh.
