Simple. Ask me what I am doing. And do completely the opposite. Lol.
In all seriousness. My kids 529 college savings plan was one that over time did well, simply because I did not F with it. After the minimum amount to fund the account, I just do an automatic investment every month of a few hhundr d bucks.
My vanguard index funds did OK throughout the years until, again, I F’d with them before the elections. I’ve been trying to slowly reverse that damage.
