Taking inspirations from actor Anil Kapoor, actress Katrina Kaif feels concentration and focus are the two most important things that every actor needs to follow.

"During the shooting of 'Humko Deewana Kar Gaye' Anil used to tell and teach me as to how concentration and focus are important things in an actor's career. This is one thing that I will not forget and feel that will flourish my career," Katrina said.

The actress, who has worked with several senior and experienced actors like Akshay Kumar, Govinda and Salman Khan, feels blessed to have such talented co-stars from whom she has learnt a lot.

"The more films you do you get more experience and then you get to know what you want to do as an actor, what different and special thing a role or a script you are looking for," she said.

Katrina who plays a lead role in 'Ajab Prem Ki Ghazab Kahani', a romantic-comedy, opposite Ranbir Kapoor, said, "I was kind of chilled out and had fun while shooting with Ranbir. He is a good co-star who is passionate about his work and does not have ego."
