Q. How would you describe Mark Watney's personality?

When Watney wakes up stranded on Mars in a hopeless situation we find out what he is really made of. Mark Watney's personality is defined by never giving up, working hard and by his silly , childish and sarcastic sense of humour. For instance, when Watney is working on repairing the atmospheric regulator he says, "Hey, let's allow a fatal lack of oxygen that will make everyone drop dead!". When Watney's not working to stay alive he entertains himself with Commander Lewis's '70s tv collection. After watching the Duke's of Hazzard Watney says, "And seriously. . .it's clear the the General Lee can outrun a police cruiser. Why doesn't Rosco just to the Duke farm and arrest them when they're no in the car?".
