Simple and probably obvious to many but I was quite old until I learned this. Depending on who your parents are, many kids have no clue this is even possible, getting a job and a salary is the only thing they know (and I knew growing up) so it is important to tell your kids about this sort of thing, I've told my oldest already and he's 3.
If you grew up true middle income or poor in the US it is extremely hard to value equity as an adult. Then, if you manage join a company that offers equity, it can be a mental struggle to buy your options even though you have plenty of cash on hand.
