If you ever feel that your dreams will never be fully realized, you should see what Chris Pratt wrote about never giving up.

Pratt posted the message to his Instagram a few days ago after being "up for over 77 hours."

Despite the lack of sleep Pratt managed to leave a poignant message about chasing your dreams.

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 iI'l 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."

He knows a thing or two about chasing your dreams and never giving up. Pratt has had a huge couple of years, starring in Jurassic World, and Guardians of the Galaxy while voicing the lead character Emmet in The Lego Movie.
