Did you ever watch Looney Tunes cartoons as a child? Cartoons like Bugs Bunny or Duffy Duck or Wile E. Coyote and the Roadrunner? If my memory serves me right, often the theme of the episode was that someone was trying to catch someone else (like Coyote trying to catch the Roadrunner, he rarely does anything else), and the one trying to do the catching always ended up injured and making a fool of himself.
And it was funny, I admit. But I never thought of those cartoons as anything more than entertainment - and I suppose the creators themselves wanted only to amuse children and maybe teach them not to kill animals - until yesterday when I saw a quick scene of one episode from approximately the 80's in which a hunter was trying to catch Bugs Bunny by running through a hollow tree trunk and Bugs rotated the trunk so that the hunter would end up running out over a cliff and onto thin air. Walking over a cliff and not realizing it before it's too late is, in fact, a recurring theme in the Looney Tunes cartoons.
What makes the theme special is that those walking over the cliff never fall down before they realize they have no more ground under them.
In the Bugs and hunter scene I saw yesterday the hunter even starts to sweat with anxiety - because he knows he's hovering in air - and tries not to look down. Not until he finally actually looks down, does he fall. So, theoretically at least, the hunter, or Wile E. Coyote or any other character, could just ignore the fact that nothing supports their weight from underneath, and walk over a canyon like if were solid ground.
Think about it with terms of your life.
If you have an endeavour you're working on in your life, an endeavour that has but a slight chance of success - like you were metaphorically walking on air - merely ignoring the fact that the success rate is low and grinding like nothing was wrong might let you achieve the success against the odds - metaphorically, to cross the canyon and make it to the other side unharmed.
How about that.
