Manchester City still lead the English Premier League points table with 37 points, Man Untied is 2nd with 29 points and Chelsea is 3rd with 26 points.
"The Premier League is so tough", Guardiola told BBC Sport.
"I was not talking about winning, losing or drawing the game, I'm talking about not giving up, being positive all the time, being focused on what we have to do".
The free-scoring Citizens travelled to the Kirklees Stadium on the back of a scintillating run of form, having picked up wins in all but one of their matches across all competitions this season, a 1-1 draw with Everton on the second day of the Premier League campaign.
While their seemingly unstoppable rise has been built upon their irresistible attack, it was resilience that saw beat promoted Huddersfield for their 18th successive victory.
Sterling has now scored 12 goals in what has become his most prolific season and Guardiola reckons the England ace has the world at his feet. "I am impressed but he is still 22 years old, he can do a lot of things to improve and if he wants to learn we will be there to help him".
However, Man City equalised through a Sergio Aguero penalty and, with just six minutes left of the game, struck the victor through a lucky Raheem Sterling deflection.
"It's not just about how many goals he scores or how many chances he creates", Guardiola said. We played against a tough team and winter has come, but we did it and now we can continue. "We are so happy with his performance".
