In the personal note, Pratt opens up about how grateful he is for all the opportunities that have come his way, all while encouraging his fans to never give up on pursing their dreams, no matter how out of touch they may seem.
"It's 3:20am. I got picked up for work at 6:45am yesterday," the caption on a photo from his early morning drive read. "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," he continues. "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."
The 36-year-old actor has come a long way since his days on Everwood and Parks and Recreation, and noted that he hopes that by seeing his journey in the spotlight, others will be inspired to go after their own goals.
"I am doing what I love. It doesn't feel like work. Even though it is. I'm having fun," he shared. "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," he added. "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."
All seriousness aside, Pratt isn't afraid to have a little fun every now and then. Last October, the resident goofball said the hardest part of playing the role of Owen Grady in Jurassic World was keeping a straight face.
"For me, the biggest challenge is to not be goofy, because it's my natural instinct to be a goofball," he revealed. "Before every take, I would have to do this little ritual to be like, 'Don't turn into a dumbass halfway through this take!'"
