Chris Pratt always knew he would be a successful actor, because he never had a plan B.

The 36-year-old actor first made a name for himself on television show Parks and Recreation, before achieving leading man status thanks to films such as Guardians of the Galaxy and Jurassic World.

Chris took to his Instagram page in the early hours of Wednesday morning (27Jan16) to tease fans that the upcoming Guardians sequel is going to be incredible, while also revealing how proud he is of upcoming movie Passengers, in which he stars alongside Jennifer Lawrence.

Alongside a picture of what appeared to be his commute, Chris wrote: "It's 3:20am. I got picked up for work at 6:45am yesterday. I'm not good with math, especially after being up for approximately 61 hours but I think I've been up for over 77 hours. I did a table read for Guardians of the Galaxy 2 this morning and then shot all day on Passengers and just now wrapped some 144 hours later. Weirdly both films, which I'll be shooting back to back, are being shot in Atlanta at Pinewood studios. We have the best crew. Total rock stars busting their asses. And the stuff we're shooting. My God. I can't wait for you to see it. I go back in in about 8 hours to do more."

Chris also has a happy personal life, and is father to three-year-old son Jack with wife Anna Faris, who are bound to be waiting for him when he gets home.

As his lengthy Instagram post continued, Chris told his fans that they should never give up on their dreams, and should always believe in themselves.

"I am doing what I love. It doesn't feel like work," he added. "Even though it is. I'm having fun. I'm overcome with joy and gratitude. I felt like posting this to say to anyone out there chasing your dream... Fifteen years ago I felt the same passion I feel today, but I had very little opportunity. I had to hustle hard and go hungry. I had to eat sardines and figure out how to get gas money. And I never had a plan B. I never stopped believing. Ever. Don't give up. Apply constant pressure for as long as it takes. It will break before you do. Go get it."
