What weird life hack actually saved you real money this year

[kyman1]

Share a trick (could be a small trick done daily) that really helped you saved money or prevented you for losing money, diet, not doing going out, or choosing a better option of something?

Refueling vehicles with gasoline in the morning or evening when temperatures are lower and fluids are denser.

Will give you more gasoline per liter / gallon.

Not a weird hack, nor I'm considering it a hack lol but for me, personally, it helped me plan out how my normal day will go and separate the money I get from my savings, subscriptions and other personal expenses.

I know it's not weird or a hack but hey, it helps you create a system for yourself wherein you achieve on all aspects (diet, saving money, vacations, goals and stuff you wanna buy). It's quite easy but the hard part is the consistency and discipline.
