Sharma stamped his class by hitting an unbeaten 127 on debut as India recovered from a top-order collapse to take a firm grip of the first Test against the West Indies with a 120-run first-innings lead at the Eden Gardens.
"Being a sportsman, there are a lot of inspiration to take from so many sportsmen around the world. You got to look at Michael Hussey... He made his debut at 30. There are a lot of other cricketers who waited for their opportunity... So I'm no different," Sharma told reporters.
The Mumbaikar said he knew his time in Test cricket would come.
"I know there was a phase when things were not going my way. But I never put my head down. I just wanted to focus... I knew there would be a time when runs will flow. I just waited, waited... Kept working on my game hard and today I'm really happy what's happened."
"I was a bit disappointed about what happened in 2010. I just wanted to have all my focus on this Test. Finally, it came. Whether it came after three years does not matter.
Asked whether he's in the form of his life, he said: "I really don't know. Whenever it happens you got to be proud, you got to take that.
