Bret Hart's response to Flairs comments

[The Outlaw]

Wrestling wasn’t just a job for me, it was the only way of life I knew long before either Hogan or Flair laced up a pair of boots and took their first wrestling lesson to see what it was like.

We know it was more than a job from your constant bitching, but whats the latter all about?

The latter part is about how Bret was born into wrestling. He watched his father train wrestlers from the time he was born. You can say that the first thing he knew was wrestling maybe.
