Though plenty of people crave instant gratification, Leonard Nimoy knew better. The actor was in his mid-thirties by the time he secured his breakout role, that of Spock on Star Trek: The Original Series. However, the actor was grateful that such thundering fame hit him when he was well into adulthood.

“It would be pretty difficult if I hadn’t had sixteen or seventeen years to find out who I am,” Nimoy said during an interview with the Montreal Star. “I pity any kid in his teens that this happens to. It’s like building a skyscraper and starting on the 20th floor.”

Still, he was sure to enjoy the spotlight when its bright light shone on him. The television series led to a lifetime of fame. In addition to working as an actor, Nimoy also became a writer and director.

“Me, I enjoy the recognition,” said Nimoy. “I’m not tired of it yet. I probably won’t be for a long time. I also realize that it could stop in six months. It’s an extra, a bonus; I didn’t expect it.”

Interestingly enough, Nimoy had his own reservations when Star Trek first began. “I was anxious for steady work,” said Nimoy during an interview with the Tribune. “But I took myself seriously as an actor and was concerned about what might become of me if it didn’t work.”
