Washington, Nov 16 : Hollywood actor Mel Gibson says he is always looking to improve himself and insists the best suggestion he ever received was to take up gardening.

The ''Braveheart'' actor - who recently became a father for the eighth time when girlfriend Oksana Grigorieva gave birth to daughter Lucia Anne - says the best advice he was ever given was to dig ditches.

The 53-year-old star now grows vegetables to become a better person.

"Some of the best advice I was given, a long time ago, was from a guy who said, ''You want to make yourself better, go and dig a ditch.'' So, a lot of that''s been going on, ditch-digging, vegetable-growing," Contactmusic quoted him as saying. (ANI)
