The 25-year-old is now back to full fitness, after moving to Everton from the Gers during the summer.
"The whole way through most of pre-season, I've enjoyed it more than most footballers enjoy pre-season just for the fact I had been out," he said.
"Now that I'm back involved in games, the games can't come quick enough."
Naismith has played his part in Everton's good early-season form, which has seen the Toffees take six points from their opening three matches.
"I think that was something the manager made a conscious point of stating to the players, that he wanted us to start well," he said.
"We showed, especially in the Manchester United game, we were willing to fight and got our just rewards with a good 1-0 win and we pushed on from there in the cup game [beating Leyton Orient 5-0] and against Aston Villa [won 3-1], although obviously last weekend wasn't a great result to finish it off."
