“I only work hard when I like the teacher.”
That’s one of the worst things you can say about your work ethic. You’re telling your parents, counselor, or college that you need someone else to summon your motivation for you. That’s like applying for a job and saying, “I only work hard if I have a great boss.” Why wouldn’t the company pick someone else who’s proven they can produce great work whatever the circumstances are?
Learning from a great teacher is a gift. Even the best students often find that certain teachers inspire them to learn and accomplish more than they thought possible. There’s nothing wrong with celebrating those circumstances, and any college would be glad to see that you make the most of it when a great teacher is put in front of you.
But don’t get in the habit of waiting for someone or circumstances to hand motivation to you. It’s called self-motivation for a reason.
