Nobody likes to ponder their own death. However, death is inevitable (at least until someone makes some huge scientific breakthrough). If you die without a will, your assets, which includes your money, possessions, real estate, investments etc., get paid out to your beneficiaries according to the laws that are in place when you die. Those laws are not affected by any wishes you may have had beforehand. By preparing and signing a valid will, you get to decide how everything that you have worked so hard for will be distributed. It also allows you to do some estate planning, which may limit some taxes payable on death.
