Steve Cotterill was staying grounded after seeing Bristol City make it maximum points from their opening two League One games.
Cotterill's promotion favourites had to come from behind to beat battling Colchester, Aaron Wilbraham netting twice after George Moncur had shot the visitors into a ninth-minute lead.
Cotterill said: "It's a decent start, but no more than that. We can be fitter and sharper in our thinking.
"We have a new pitch, which is a bit quicker than the players have been used to and it will take time to adjust.
"But I'm pleased with the effort of the players and feel I have a really good group."
Cotterill has urged striker Wilbraham to be more selfish in a bid to boost his goal tally for City and the player's response has seen three goals in his first two starts.
The City manager added: "Aaron has been more known as a goal-maker during his career, but I have told him to think of himself more and grab a bit more glory.
"He will create for us and be worth his place even when he doesn't score, but I'm delighted to see him hitting the back of the net.
"We will take risks looking to be entertaining and if that means conceding now and again so be it."
Colchester took a ninth-minute lead when skipper Sean Clohessy set up midfielder George Moncur to net with a low right-footed shot from 12 yards.
But City hit back less than a minute after the break. Greg Cunningham's low cross from the left was converted by Wilbraham with a clever right-footed finish.
The centre-forward was on target again after 68 minutes, rising at the near post to nod home as goalkeeper Sam Walker came off his goalline without reaching Wade Elliott's cross.
Colchestrer manager Joe Dunne could not hide his frustration.
"It was a lapse in concentration. Several mistakes contributed to the winning goal," Dunne said.
"Other than that I was delighted with my young team. We have made one of the strongest teams in our division fight all the way for their victory.
"I was particularly pleased for young Frankie Kent at the back. His performance will make me think twice about how to spend the small amount of money for a loan signing that I have available.
"We are very disappointed and frustrated not to have taken anything from the game.
"There were so many positives, but a couple of bad moments have cost us.
"When you consider that we had six players out injured and another one suspended it was a great effort by the lads."
