Have you heard about this certain belief that you shouldn’t fold your bills. Some folklore are saying that your bills shouldn’t be folded and should be placed neatly inside long and lengthwise leather wallets. You should see to it that your money remains clean and you should also avoid writing something on it like names, numbers, symbols, etc. as it is believed to bring bad luck.
These are just beliefs though and you won’t lose anything if you’re going to follow it. Organizing not just your money but everything that you have can make your life systematic.
