Chris Pratt didn't get to play Owen Grady in Jurassic World without a lot of hard graft first

Chris Pratt has shared an inspiring message with fans hoping to follow in his film star footsteps, encouraging them to stick at their dreams.

The Jurassic World actor was finally heading to bed after being awake for 77 hours working on his next two movies, Guardians of the Galaxy 2 and Passengers, when he posted the reflective advice on his Instagram page.

Here’s what he had to say to any wannabe actors [or wannabe anythings] out there:

“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.

“I am doing what I love. It doesn't feel like work. 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.”

Pratt earned his break playing jock Bright Abbott on four seasons of TV series Everwood from 2002 to 2006. He bagged the role of Andy Dwyer in Parks and Recreation in 2009 while his film career began with 2008’s Wanted.

The 36-year-old auditioned for the part of Jake Sully in 2009 box office smash Avatar but missed out, forcing him to rethink his ambitions.

“They said they want somebody that has ‘that thing’, that ‘it factor’,” he said. “I walked into that room knowing that I did not have that thing and I walked out thinking I would never have that thing, probably.”

Luckily, he didn’t hang around waiting tables at the Bubba Gump Shrimp Company restaurant in Maui for long.
