Lewis said that he wants to hit top form as the World Championship comes up and for the TV tournaments coming up.
"I think I've had an up and down year," Lewis told Sky Sports.
"I won a Pro Tour, I've made a few semi's and finals but as a whole it can be better, I've just got to keep working at it really.
"This is the time where you want to start hitting top form now, this is the time you have to work really hard in building up towards the World Championships, there's that many TV tournaments now coming up."
