i'd bank £500k to get the interest to give me a good monthly income.
i'd spend £100-£150k on 2 houses(one for me and one for my mum)
25k on a car.
50k to get a nice HC setup. couple of nice PC's and a laptop
buy a season ticket to liverpool.
do a big round the world trip and watch every F1 race in a season.
go on holiday a few times a year.
that would do me tbh
