Kane equalled Alan Shearer's Premier League mark of 36 goals in a calendar year, set in 1995, with another hat-trick at the weekend in his side's 3-nil win at Burnley.
Kane's fifth hat-trick of the year lifted him to 93 Premier League goals in total, but he has some way to go to match Shearer's all-time best of 260.
"Of course you dream about it, but I'd be silly to look that far ahead I think," Kane said. "I've still got a long way to go. A lot can happen in football.
"Hopefully I can stay fit, stay sharp and we'll see what happens. Maybe if I get to 200 and I've still got a few more years left then I'll start thinking about it.
"But for now I'm concentrating on each game. I've had a great 2017 and hopefully, for me, it's an improved 2018 and I get even better."
The England striker will bid to break Shearer's calendar-year mark in Tottenham's home game against Southampton, but insisted the team comes before any personal landmarks.
"Of course, always," he said. "I've always said that and that will always be the case.
"I'm the striker, so a lot of the time I get the praise and get spoken about, but it's so important that the team does well.
"But now, obviously equal, yeah I'm full of confidence going into Tuesday. But most importantly for me it's the wins that matter and Southampton's going to be another tough game."
