The great thing is you can read the subreddits casually for ~3 months and learn everything you need to know to autopilot your financial plan for decades if you go the boglehead route. After that you mostly need to pay attention to major changes in tax law and entitlements.
I still read them all the time but I haven't learned anything new in years.
There's much better advice on /r/fatfire in terms of more advanced investing and tax stuff, but you have to sift through a lot of not-so-humblebragging posts. There is so much to learn outside of the "make a 100k-200k income and put everything into three securities" even if you don't use it. Real estate investing, entrepreneurship, angel investing, trusts, different corp-types, estate planning, etc.
And little things like that can help in the long run.
Boglehead advice agrees, with an explicit principle of “Never bear too much or too little risk”, suggesting 30-40% bonds in your 40s and the rest in stocks.
I think more people underperform from being too risk-averse than under-perform from having too much equity exposure and having an unfortunate overlap of a large expense and a downturn in the market.
I'm fairly risk averse and don't totally believe their leverage calculations. But it did convince me that any non-negligible bond allocation is probably suboptimal.
You talk about maxing out your 401k, but have looked into you maximizing your income to the be able to save more?
(Of course money is not the only important thing in your life)
They’re mostly bogleheads so are a little risk averse, but for most that’s probably the right move anyway.
