re: Saving money 101

Make a budget and stick to it. Invest the difference. Calculate your savings rate, then start aiming to bump it up by 1% every month until it hurts.

Go through Vanguard for all non-employer based investment accounts and stick with their ETFs/funds. If you don't prefer Vanguard, be mindful of fees/expense ratios at other companies.

Set aside money for an emergency fund. Things happen.

Invest all of your raises.

If you're going to get married, find a partner that is on board with your financial goals. Don't marry one that isn't.

Maximize tax-advantaged accounts such as 401k, 403b, 457b, HSAs, Roth, Traditional IRA, etc.
