> You should always have 18 months of expenses saved

I've never seen this sentiment on r/personalfinance. It's typically no more than 6 months, usually a 3-6 month range. Your money is (on average) better invested and the only reason to go beyond 6 months is if you really, really need that for some extra peace of mind and numbers/data don't mean anything to you.

> Look how smart I am for having a mega-backdoor roth ira instead of a regular 401k like all the idiot sheeple.

This is also uncommon.

> I still think having a relationship with a financial advisor you trust is better than taking advice from strangers on the internet.

Why not encourage people to do their own research? How much more can you really eek out from a financial advisor?
