The Gunners moved five points clear of Manchester City at the top of the table with a resounding 4-0 win over Everton at the Emirates Stadium on Wednesday.
Goals from Bukayo Saka, Martin Odegaard and Gabriel Martinelli's brace did the damage against the Toffees.
The Gunners are pursuing a first league title since 2004 as well as a return to the Champions League for the first time since the 2016/2017 season.
A 3-1 home defeat to Manchester City last month saw the champions briefly overhaul Arteta's side at the top but the Spaniard is impressed by the response shown so far.
Asked whether Arsenal's thrashing of Everton made them title favourites, Arteta said: "You know my answer there!
"What I like is that everybody has the enthusiasm to do it, and we're not going to stop that – we have to promote that.
"But the way to promote that is by looking at this game and understanding that we have to do a lot of things better, especially in the first half.
"We can play better and make sure we prepare really well against Bournemouth, because that's going to be a tough game."
Asked how Arsenal could find the mental strength required to beat City to the title, Arteta said: "It is something that we have to train and discuss and build.
"It is not easy, but a lot of time it happens through experiences and most of the time they are experiences that you don't want to go through, but the calendar and fixtures are going to give that.
"Sometimes you are where we are now, sometimes it is three points [difference], two points, minus two – it is going to happen and we have to live with that."
Arsenal are back in action against Bournemouth this weekend.
