How would you spend a large gift of money

A co-worker of mine asked me this question the other day at lunch and it spurred a great discussion between everyone, so I thought I would ask the same to all of you. Curious to see what types of responses I get.

• You are gifted four different amounts of money - what would you do in each situation? (retirement is an option): 500k, 1M, 10M, 20M:

• Personally for me at 20M I think I would retire, certainly not at 500k or 1M given I'm only 23 (I do have a lot of friends who said they would retire at 1M), but 10M would still be tempting. I have an ambition for entrepreneurship (as I know many of you do), but the risk factor of leaving a six figure job still just is such a major leap. At the early levels I would likely invest the 500k into a home, 1M into a home and maybe try to start something on the side, but at 10M I had no idea what I would do as the potential becomes limitless. I said I would likely put about 1-3M into PE as an LP, then another 2-4M into public equities (totaling around 50%), keep roughly 500k-1M to fund a few years of travel and into potential investments as they arise, and the remaining into RE or into funding business ideas that present themselves. 

Very curious to hear what y'all have to say.
