Under your mattress
Many have preached against keeping your money under your bed due to disaster and theft fears. But keeping a small pile of notes under your bed should not be a bad thing as it is a form of investment against the unexpected. It essentially saves you from the hustle of making a trip to the bank or ATM in case of an emergency at home or outside the home where a family or friend needs help. Knowing that there is money under your bed also gives you some sort of comfort and convenience as it is readily available for you as and when you need it.
