Indeed, the young striker suggests that being in a position where he's uncertain about his future at the club - a position he's been in before - gives his play that extra edge.
He won't face that situation this season though after signing on the dotted line and extending his stay at the club recently.
Lee, 20, will add further experience to his CV with a spell in the Conference when he joins Stevenage for a month in a loan deal completed today.
"The pressure helps in a way because it gives you that extra incentive but now I've got it, I can relax a little more," he said of his new deal at Spurs.
"But I won't relax to the extent that I'll sit back and think I've made it. I still want to push on and do well."
An all-action striker, Lee has impressed in reserve team action this season and, most importantly, has showed a renewed confidence in front goal.
That has earned him call-ups to the first team squad and a place on the bench for the Premiership clash at Charlton.
"I've been pleased with my season," he added. "I did okay at the start of the season, had another good spell around Christmas, scored a few goals and although I've been on the bench lately, I've been pleased overall.
"My game is all about confidence in front of goal and I'm happy with how it's gone, I wanted a few more goals and I've done that.
"I'm looking at getting a good pre-season under my belt, try to get involved and go from there.
"Making the first team squad is the last step but the hardest step. I'll keep plugging away and see how it goes."
Lee Barnard admits that wrapping up a new deal has taken the weight off his shoulders for the rest of the season - not that he'll be relaxing in any way as heads for a month's loan at Stevenage.
