Massive jump in salary, need advice.

Hey all!

Recently I accepted a senior leadership position with a new company and went from 105k salary with a 30k bonus to 210k salary with a 100k bonus. This comes with roughly 60k worth of RSU’s as well. This position also comes with a relocation from a high cost of living area to a low cost of living area. They are giving me 30k in relocation, and 30k in sign on bonus.

I have 4 kids, and my spouse stays at home with the kids.

A little backstory on me, I was raised quite poor, I was never taught about finances, and I never saw myself making money like this. I earned this promotion through long hours, hard work, and lots of just saying yes. I have no college education.

We lived a modest life with a modest home in HCOL on the old salary, but we never were able to save for the kids college, or put enough into retirement(Spouse and I are both 39). We have a bit of making up to do it terms of saving, but we have zero credit card debt, both cars are paid off, we will be selling our current home for a very small profit(purchased a year ago).

How do I turn this new money into generational wealth?

How do I not mess this golden opportunity up?

Please give me all the advice!
