It's always on a sliding scale. You can be a 10, you drop to an 8, go up to 9. Phil Ivey, has a net worth of over $150mil in wins, endorsements, partnerships. At a time he was best in the world, cash games, underground games. Where he is at now, no clue, to say he was never a "10" for a period of time, pleeeeeaaaseeee!
To not point to a Phil Ivey, Michael Jordan, Tiger Woods, Mike Tyson, Bill Gates any of these monsters in their respective fields in a respective period of time and when they have peeked sure they're a "10", they may not maintain it but yeh you give it to them.
You can lose hands, lose tournaments and still be a "10" in poker. In poker when you create such fear from your success alone that people are petrified of you before the cards are dealt, you're a "9" when they finish in 1st, "10".
Ready to re-calibrate your "8"?
