Actor Jake Gyllenhaal says it is in his "ancestry" to always work hard and push himself.
"It's part of my ancestry, I think, somewhere. My grandfather on my mother's side was second-generation Jewish American. His father was a tailor from Poland, and he became a surgeon. He was the pride of his family. My father is from a long line of hard-working Swedes.
"Both were men who got up at 4.30 in the morning to start work. Pushing yourself both physically and mentally has always been a part of my life. From an early age, my dad would wake me up early to go for a run.
