Spurs swept Watford aside at White Hart Lane thanks to Heung-min Son's brace, plus strikes by Dele Alli and Eric Dier.
The north Londoners, who are unbeaten on home turf this season, were also boosted by Harry Kane's early return from injury.
Spurs have coped well during their talisman's absence and Pochettino is convinced his players must continue to share responsibility in order to achieve collective success.
"It means a lot - the team and the squad. All the players feel important during the season. It's not about who plays - it's about playing for Tottenham," Pochettino insisted.
"The badge is the most important thing and we must always show that we are a team.
"Football is going in a completely [different] direction to 10 or 15 years ago and today it is a collective matter more than before.
"If you don't show a strong mentality with 24, 25 players and you are not capable of making all [the players] feel important in the project it is so difficult win titles," he added.
Tottenham's latest victory has moved Pochettino's side to within four points of pacesetters Chelsea.
Antonio Conte's men, who face Bournemouth this evening, remain in the driving seat but Pochettino is adamant Spurs are on the right path towards silverware.
"I think it is important to build that winning mentality and believe that it is possible to fight for the Premier League and different titles.
"We have a lot of work to do. It is not easy but we are excited about the future of this club," he added.
