I make sure I keep the temptation in check by giving the high-interest account a fun name that hints at a future splurge instead, hah! Something like "Rainy Day Fun Fund" or "Vacation Vibes Account" makes it sound more appealing than an emergency fund and also helps me mentally separate the money from my daily accounts. Also, I try to keep a fixed amount transferred monthly rather than dip into it randomly, that way I know approximately how much is in there but don't temptation isn't too great either! It's a trick but one that works for now.
