Can you think of a time when you wanted to do something but were too nervous to try? What did you do

If I go to an amusement park, the ride I must ride is a roller coaster. So, I like to ride a scary and high roller coaster. But I was about to go on a roller coaster ride that is said to be the scariest ride at the amusement park I went to. I saw the roller coaster running in front of me, and all of a sudden, I got too nervous. Umm, for some reason, I didn\'t want to ride that roller coaster. So, I was thinking about whether to ride it or not, and I said for the first time that I wouldn\'t ride it because I was so nervous. And then I tried to ride it, I took a deep breath and thought about it again, but in the end, I couldn\'t ride it.
