The Norwegian striker is Manchester City's highest-profile signing this summer and is relaxed about adapting to playing in the English top-flight for the first time.
In an interview with Sky Sports, Haaland said: "We will see about settling in.
"People can take time, people can come directly into it. We have to see, but I'm not concerned. That's life as a footballer - you have to live with it.
"You are a kind of entertainer. You get judged every single week for what you do on the pitch and you have to deliver and do your best.
"For me as a striker, this is something I cannot stress about because if you think too much, you might end up doing things you don't want to do.
"It's all about trying to enjoy, live in the moment. People talk about what you did a year ago, but it's the next game that counts."
Haaland, 22, is one of the world's most promising players after a prolific career so far but thinks he will get even better at City under the tutelage of Pep Guardiola.
He said: "(I can improve) everything. If you think I'm good at one thing, I can always get better.
"This is something I have to do. As a young player, playing for Pep Guardiola, playing for the best club in England, I have to keep developing and get better at a lot of things. That's what I like a lot about football, you can always develop, you can always get better at the game.
"Part of the game is to get out of your comfort zone which is something I've been doing and something I like because then you develop more as a human being as well."
