When you practice anything, it's helpful to find all the "single points of failure." Meaning, that one thing that could unravel the entire project.
In your business, it could be making sure you have all types of insurance to handle any possible mishap.
In your piano practice, it could be handling that passage you know is always a problem. So when you perform it for an audience, you know you'll be good to go.
In essence, practice like you're the owner of the Death Star.
Remember the Death Star from Star Wars? The spaceship so powerful it could destroy planets?!?
Except it had that one pesky weak spot that blew it to bits later on.
Sometimes the weak spots can show up in the most unexpected places.
I once played a concert with a cellist. He had extremely high standards. He insisted every rehearsal be at least two hours long. Every single phrase played with the perfect nuance, or it had to be done again.
He needed everything to be polished and professional as possible.
So, what happened on concert day?
He walked out on stage, having forgotten to wear the jacket that went with his suit.
Did it ruin the performance? Of course not.
But, did it sully his vision of the perfect concert? Of course it did.
Check your weak spots. You never know where they'll creep up on you.
