10/10 would slave away at a startup again (actually that's a lie, once was enough). We didn't owe any money other than the original mortgage, so there wasn't really anything else pressing to spend it on. Already owned a number of guns, motorcycles, and a basic sports car. No real plans to spend the rest, it's in the bank/bonds.
Basically I'm still living the life I always have, I just have a giant workshop now in which to play with my toys and pursue my hobbies. I think if this had happened 15 to 20 years earlier in my life, I'd be looking at things differently, but at this point I just plan to retire a bit earlier than I would have and not change much else. My father was also very savvy financially, I suspect he would have some pertinent ideas.
I now work for a small company as an integral cog in a relatively low pressure environment. I get to build things every day, come and go as I please, and my contributions are respected and valued. It's lovely :-)
