I noticed quite often that there always seems to be less money in your wallet than you think there is than more. In my case the reason for that is that money usually comes in once and goes out multiple times-and I have a tendency to forget 1 or 2 of those times. I always remember how much I put in but I don’t always remember how much I put out.

A lot of people take money out of their wallets or purses to make a payment-sometimes they overpay by accident. A way to avoid this issue is to take the amount that you need to pay calm deducted from what you have, and then pay yourself the difference and then give them the rest. Period of course you need account what you’re giving them as well anyways as a second measure. But this way you most certainly will never come up short or overpay someone.
