Just don't try and tell him that he's arrived as an AFL footballer.
Jamison is proud of the way he's had to fight and scrap for a senior berth and he vows to maintain that rookie hunger.
"The day I stop trying to do that is probably when I'll get the flick at the end of the year," he says.
A similar philosophy has seen the full-back hang on to his No.40 jumper.
"I don't think I'll ever see myself as having 'made' it. I certainly don't view myself as having made it now. I've got a long way to go. I've only played 21 games and I'm still a long way off. I've got a lot of things to work on."
Jamison had operations on both shoulders in the off-season which has held him back from competitive work until now. But that hasn't stopped him adding six kilograms of muscle to his frame and getting the requisite miles into his legs.
Already adept at defending the lead, he has high hopes the extra strength will allow him to hold his own standing one-on-one with some of the power forwards of the competition.
Like a lot of full-backs, Jamison was a forward until late in his junior career and he admits holding down one of the most thankless positions in the game has taken a while to get his head around.
"It is very stressful and a bad performance can get highlighted more than anywhere else on the ground, but that's a bit of a motivating force as well," he says.
"I hate getting goals kicked on me and you really don't want to see the bloke you played on in the paper the next day.
"I'm the last person you want to hang around with the night before a game. I get pretty stressed and worried about the next day, but that's all forgotten when I run out on the field."
Jamison is currently studying for a commerce degree which, along with other pursuits outside football, he feels allows him to lead a balanced life.
"I try not to get too involved in all the hype that goes along with the AFL," he says.
"I've always looked at my heroes of the game like James Hird and he was pretty successful off the field and guys around the club like Simon Wiggins, who has a really balanced life – they enjoy their football so much as a result. I just try to take a leaf out of their books.”
Right now, though, Jamison is more than happy with his lot in life.
"I wake up in the morning and I'm happy to do what I do. I know that I'm going in to have a kick around with 40 blokes that I get along with really well.
"That's how I look at it. I don't really look at it as a job to be honest – it's more about the pure enjoyment of getting up in the morning."
