Good post. Incidentally, I don't think most millennials need this advice - in fact, they may need the opposite. They (we) already vacation 4.2 times a year, or more than once every 3 months, which not only seems ludicrous and entitled to me but explains why they have no savings, can afford no homes, and live in their parent's basement in record numbers while trying to stay on their parent's health insurance.
I'm happy to say that I don't belong in this list but I know many who do and they aren't doing any thing to change it sadly. :(
I'm not even passing judgment, either. This is kind of what you would expect if you raise a generation that thinks it is OK to spend 6+ years and 200+k getting a degree in Gender Studies. No rational cost benefit analysis really ever took place. It's like we all went to school and majored in jazz guitar; I'm sure it was personally enlightening, but now we're working at McDonald's and don't have a housing down payment (as a collective demographic).
