The 41-year-old actor, who is currently single and has never married, says he made a decision to put work first in his life after seeing many of his family, including his parents, who separated when he was 10 years old, go through divorces, reported Femalefirst online.
"I come from a large, large family with many divorces so I chose not to go down that route straight away. Instead I essentially got married to my career," Renner said.
"The 'Bourne Legacy" star also said that he accepted his unconventional looks from a young age as he was always taught to think himself beautiful.
"Aren't we taught as kids that we're beautiful because we feel beautiful and not because someone else says so? You don't look like the model on the magazine cover but you can still be beautiful, so I can't say I really want to change anything. I'm happy with the flaws I have," he added.
