The 47-year-old actor, who last year celebrated 20 years in films, said that the industry has changed vastly since he made his first film.
Speaking to IANS, he said: "When I came in [Mumbai] that time it was only about romantic films. Now things are changing and the journey has been great. I will keep working till people want to see me."
"I feel I was in the industry at the right time and I am very proud and thrilled that lots of things are changing with films," he added.
The actor, who is reportedly penning his autobiography, said that while he has realised many of his dreams, he still has many ambitions left to fulfil.
"Everyday a new dream is born. It is nice to keep on dreaming. I dream to make different films, I want to see my kids healthy," he said.
"But I feel you have to be rooted in reality before dreaming. Believe in reality at the first place and get your education first."
Khan's next release is Chennai Express with Deepika Padukone.
