LPT:Set up a separate savings account you can't easily access, and name it something inconvenient like "DO NOT TOUCH — EMERGENCY ONLY"
Sounds silly but it works. Having your emergency fund sitting in the same account as your regular spending money makes it way too easy to "borrow" from it for non-emergencies.
A separate account, ideally at a different bank so it's not one tap away, creates just enough friction to stop impulse dips into it. #entertainment
