Kennedy wanted to give an inspiring speech without being long-winded.

Kennedy was a smart politician who understood well the people who elected him. They didn't want any over complicated terms. That would set them off. They didn't really wanted anything unsubstantial, since he had to show that he was worthy of the position.

He found the middle term between those two quite well and managed to inspire the nation and to help create a sense of patriotism and cooperation.
