Ryan Reynolds would never tell people how to live their lives.

The 34-year-old actor is passionate about environmental issues, and while he wants to raise awareness of causes close to his heart, he doesn't want to become "self-righteous".

In a profile of himself for Entertainment Weekly magazine entitled 'Why I'm Obsessed with Ryan Reynolds, by Ryan Reynolds', he wrote: "Reynolds is also careful not to get too self-righteous, and is not one of those finger-wagging celebrities telling you how to live your life.

"He prefers to put the word out quietly, through the exciting mediums of interpretive dance and Japanese hand fans."

In his profile, the 'Green Lantern' actor also recalled his childhood skirmishes with his brothers in Canada.

He wrote: "He spent a great deal of time with his older brothers and, in turn, his brothers were very close to him. Usually within striking distance."

Ryan - who split from wife Scarlett Johansson in December after two years of marriage - reminisced about his teenage crushes, discussing the first time he had his heart broken.

According to the publication, "her name was Finona Gorchinsky and she broke Reynolds's heart - and nearly his neck - during a school bus ride in the eighth Grade."
