Chris Hadfield is a former astronaut who was assigned to work aboard the International Space Station.
He became the first Canadian Commander of the ISS when Expedition 35 took control in 2013.
Hadfield became an instant internet celebrity when he started to share his daily life on social media.
He shared breath-taking photos as well as comical videos — including a pretty funny one of him trying make a meal in zero gravity.
Hadfield took part in a Redditt “Ask me anything” session while on the ISS. A young child asked if he had any advice for an aspiring astronaut.
This inspiring quote was his reply to the youngster.
