Heritage, legacy, family. You must serve society and its smallest part - the family. All your actions and deeds, all plans and ideas and actions must be directed and formulated in such a way that their results can be enjoyed by future generations. If you leave nothing behind, you have lived your life in vain, and this is not just a matter of sound words. You will accumulate huge reserves of experience and knowledge, wisdom and material goods, but only in order to pass it on and leave it to your children and the children of the world.
