I would advocate not making that a "really long way off" - make it sooner rather than later, I have never earned at your level, but by being a bit canny with buying and selling (and doing up property) I got rid of mortgage debt at 40, not by having a palace, but a nice, sturdy house in a nice location.
This means I can indulge passions, work less, experience more. I visit a lot of people in my work as an electrician and sadly encounter quite a few who have scaled the corporate / career ladder, earned very well, purchased bug homes that have finally been paid off age 65 and that great pension is ready to go - but alas health issues mean they can't enjoy it.
Better to have less and enjoy more whilst relative youth is on your side!
