Bought Bitcoin or have tried to buy a shoebox of a house.
But I listened to all the "sensible" people and went for a graduate level program instead like an idiot, and then couldn't do anything with it for a litany of reasons. Just one family emergency or health problem after another.
The worst of all maybe could have been avoided if I hadn't been off at school in the first place. I don't regret college, but my education should have stopped there. I was finally an adult, but I still let everyone else dictate my life, right from the getgo.
