Set up a set of investment holding company to provide me with income, but continue with my life as normal including getting a job.
So long as I have enough money to do the things I want to do (which are not particularly expensive), money is just whatever to me. My parents have a decent car, so my views are not motivated by bitterness or sour grapes, but to me, a car worth £500 is the same as a car worth £500,000. It's a piece of metal which transports you somewhere.
(This said I do care about safety for my family)
