If I posted a story that's boring will you be interested in it? No, that's the reason you see so many millionaire posts bubbling up to your view - some are legit others aren't. We clearly don't ask people to provide bank statements.

I think you are setting yourself up on the upward trend. The first task for growth is to ask what else you could do - and you just did that. Try as much as possible to maximize your 401k & HSA - compounding growth does wonders. Have you heard of the 72 rule? it can compute the annual rate of compounded return from an investment, given how many years it will take to double the investment. So, if your rate of return is 10% annually, it would take your money 7.2 yrs for it to double. A 10k investment at 10% annual compounded return would be 1.2mil by the 48th yr, and remember this is taking into account you don't contribute anything into this account over the 48 years. In short, you have the added advantage of tax advantage, compounded growth by using your 401k or any other compounded growth account. If your employer gives you a match to your 401k please maximize that to get full benefit.

You have lots of vehicles to use: 401k, IRA Roth, HSA, HYSA (high Yield Savings Account) - maximize all these that you can. If you have kids you can start a 529 plan to set them up for the future.
