I certainly wouldn't consider myself a huge name or anything even remotely close to that. But I started out with a $50 deposit on empire poker and a $15 book (and have never had to redeposit).
This June is 9 years, with never having a losing month, biggest downswing being 18.5 buy ins, and I've won over $2mill from hold'em (both limit and NL).
So I guess in some people's mind (myself included) when you say "grind"...I think of the guy playing month after month after month with a low variance constantly winning strategy. Many players have won a lot more then me, but I'm not too sure there's many that can claim never having a losing month over 9 years
