Esher's Sam Ulph insists coach Mike Schmid will not let the side get carried away with their success in National One.
Esher have won 16 of their 17 league games so far, including a key victory at title rivals London Scottish.
Full-back Ulph told BBC Surrey: "Our coach has brought us down to ground straight away.
"At the end of last week we were very excited but we're only halfway through the season."
In their last three games Esher have beaten Scottish 38-15, Stourbridge 89-0 and Newsbury 56-7.
Ulph said: "We want to replicate the feeling of last week and the big games we play this year, every single week."
Esher top the National One table with 76 points, five ahead of London Scottish.
