You're waiting for your business loan to be approved.
You're waiting for a prospective client to finally say "Yes" to your offer.
You're waiting for your business to take off now that you've done what you could.
Now that you're waiting, you realize that waiting (and not knowing what to expect) is harder than anything.
Getting news that you succeeded calls for a celebration. Getting news that you failed – you can face it, re-strategize and move on. Any answer will, somehow, give you closure.
But waiting?...
Like a test, you'll either pass or fail the waiting game.
Waiting is part of the package. Not only that it reminds you that you're not in control, but you also get to realize the important things in life.
You might as well do something productive and enjoy the wait.
