I dont care how materialistic this is but.................
Buy the beach front dream home just up the road here in Sydney, then invest in holiday/rental homes in Pacific Palms, Gold Coast, Sunshine Coast, Mandurah, Clayton in SA and of course Sandy Pt. Dont know why those places

A smick windsurfing van, make Windsurfnsnow extremely happy every week and visit Maui each winter (ours).
Be with my wife and daughter.
Then buy houses for the family with the proviso that any bickering would null everything.
Then do whatever the f*** I wanted
