It's impressive to me...I took off from the game for 10 years before finding it again in my late 30's and have progressed from 4.0 to 4.5 and occasionally beating 5.0's and earning respect from ex-college players, which is pretty cool.
Wish I hadn't taken off so long and really dedicated myself to it earlier.
Jamison has many years of really high quality singles tennis in him and has made remarkable progress through hard work, honest self-evaluation, and a belief in himself. As someone who is never satisfied with staying static, I can appreciate that very much.
I'm on injured reserve now due to a couple of herniated discs and missing the game terribly. It's a setback, but I can't wait to get back out there and will continue to check out Jamison's progress.
