The 23-year-old has scored nine goals this season, including a brace in the Gunners 5-2 victory over Tottenham Hotspur after the England winger recovered from a difficult start to the campaign.
Walcott, who moved to Arsenal from Southampton in 2006, is hoping he can improve his finishing and become a vital asset to Arsène Wenger’s side.
“At times people just expect me to knock the ball and run but it is not as easy as you think to be honest,” Walcott told Arsenal’s website.
“As soon as you start doing that, the defender knows what you are doing every time. You need to change it because you can’t just be one-dimensional.
“I am always going to be known for pace, I know that. But the next step is the finishing. I have a lot of assists this season but I don’t think I am ever going to lose that.”
Walcott received plenty of criticism as Arsenal struggled at the start of the season, with Wenger’s side suffering early defeats by Liverpool, Manchester United and Spurs.
And the forward admits his desire to impress has hampered his performances at times, with a frustrated first-half display in the north London derby at The Emirates a prime example, before he inspired a memorable Arsenal comeback after the break.
“You always try but when things aren’t going for you in the game you tend to try too hard and nothing goes your way no matter how hard you try,” he added.
“A perfect example would be Tottenham in the first half. I was just trying too hard and it wasn’t quite happening.
“But then I just tried to forget about that, played as a free spirit in the second half and it happened.
“Football is a weird game; you have your ups and downs and that is the way it works. Nobody goes out there not wanting to play well, you want to put in 100 per cent but if it isn’t going for you then it’s just not going for you.”
