If you want to win against a tiger, you can’t fight like a tiger. We have hands with small nails while they have paws with big claws. We have herbivore teeth; shaped in squares. Tigers have the pointy teeth that hurt…a lot.
You don’t beat the tiger by becoming the tiger. Instead, you beat the tiger by being different. Use your surroundings, blow a whistle at it (blowing the whistle actually works. I read a book about it), and do anything else that you can.
Don’t try to beat the competition by becoming the competition. They have more experience and a larger audience than you do. Do something that the competition can’t do. Find their kryptonite. It’s there somewhere!
