The Spanish coach has enjoyed phenomenal success since taking charge of City in 2016 and declared that he has no intention of going the same way as rival Jurgen Klopp - who has announced that he is to leave Liverpool at the end of the season.
Guardiola said: "I have everything that a manager could dream of. The hierarchy support me and always have. It’s a good environment.
"I still feel good and, of course, one day it is going to finish but I don’t think about that right now."
Guardiola led City to a historic treble last season but admits that he is re-energised by the prospect of winning more trophies this term.
He said: "Winning helps you to have more energy. When you are losing games you are more tired but I see the team getting better and playing difficult opponents like at Goodison Park after the Club World Cup or Newcastle or Spurs away.
"Seeing how the team behaved (showed) me, wow, we are still together, we are on the same path. That gives you energy. You do not switch energy on or off. You have to bring energy every day. That is what I am living now."
Guardiola's City contract expires at the end of next season but he does not feel any pressure to agree on a new deal with the Premier League champions.
He said: "I think we have time. Now I feel really good, like always I have been, but football changes a lot.
"I have my opinion that when you have a year-and-a-half left on your contract it is a lot of time in world football.
"Many things are involved and extending after two years is not the same as extending after nine, it’s completely different. But still I am sitting here and I am OK."
