Spurs now sit four points ahead of fifth-placed Arsenal following their Bale-inspired 2-1 win over Newcastle United at White Hart Lane on Saturday.
They had been in a stronger position last season but faded away and missed out on a spot in Europe's top competition despite finishing fourth, as Chelsea won the Champions League to deny them a place.
Bale is determined for that not to happen again this term, saying: "In recent years we have kind of gone off the boil a little at this time of the season but I think the lads have got a lot more confidence.
"We have learned from our mistakes from previous years and now we can be a lot stronger going in to the finishing end of the season so I hope we can do it."
Bale has been in stunning form for some time now but he played down the personal plaudits after the clash with Newcastle, instead admitting he was unhappy with his performance because he missed a couple of late chances to take home the match ball.
"I was absolutely fuming (that I didn't get a hat-trick)," Bale told Spurs TV Online.
"I missed a few chances, especially the one with my right foot, but the most important thing was that we got the three points to put the pressure on the teams above us and below.
"I am enjoying my game at the moment and the team is playing well, which always makes it easier."
