When things aren’t going the way you planned look at it from a different perspective.
Maybe the purpose you always thought was intended wasn’t the purpose at all.
Like when you went the NYC. You thought you were going for the purpose of giving a speech. Then your room fell through and everywhere you turned there was another toll. So, you decided that instead of stressing over every penny and ruining the experience you decided the purpose of your trip was no longer the speech but to take the trip to NYC you had wanted – it just happened to include a speaking gig.
Instead of being disappointed by your original purpose not being accomplished you changed the purpose.
Changing your perspective is a powerful secret to saving disappointing situations.
