Live to leave behind you positive legacies that will outlive you. Because surely, you will be gone someday, no matter who/what/where you are currently. Oh! Yes, no human lives forever including you. As a matter of fact, we all are here (on earth) for a while. Now, I guess that is a reasonable reason why you should strive to leave behind you positive legacies that will be speaking for you, for years/forever after your demise.
