The Brit secured the championship in Mexico two weeks ago and heads to this weekend’s race in Brazil knowing the title is wrapped up.
His victory this season puts Hamilton level with Argentine driver Juan Manuel Fangio with only Michael Schumacher ahead of the pair on seven championships.
Lewis Hamilton is 33 and is contracted to Mercedes until 2020 having signed a new £40million-a-year deal earlier this season.
But he is already concentrating on his life post-racing, and has plans to help future generations.
“I have a lot of things that I want to do,” Hamilton told the Sun.
“I get tons of messages every day asking me if I want to do this or that and it is about focusing on which one has the most impact or is the most meaningful.
“At the moment it is focusing on racing. But as I get to the tail end of my career, that is going to shift and I’m putting in the building blocks so I can work on those things.
“Education is one thing I want to get involved in. I’d like to meet government heads and understand the curriculum they are giving the kids.
“I remember being at school and there was never a discussion with a teacher about encouraging someone to become an engineer or how to get on to that path.
“If I was to do something with schools the priority is in the UK.
“I also cannot understand how we stand by and watch all these kids trying to get into racing and parents taking them out of school.
“A lot of parents maybe home educate them but 98 per cent of those who don’t make it end up with no opportunities.
“I remember struggling at school and jeez, if I hadn’t made it, I would have fallen flat on my face — and we didn’t have a lot of money.”
Former F1 star Mark Webber believes Hamilton can match Schumacher in the years to come.
“The sky’s the limit, he still looks like he’s pretty young mentally in terms of energy and he could probably go for Michael’s record,” Webber said.
“Seven is totally on the table. Eight is only one more but the difference between seven and eight … to win the next three on the bounce is a lot.
“Seven is doable, but eight is the big one.”
