We should  never forget everything we have and all the people we love will disappear at some point. This is something we should keep in mind, but without giving into pessimism.

Being aware of the impermanence of things does not have to make us sad; it should help us to love the present moment and those who surround us. "All things human are short-lived and perishable," Seneca tells us. Source:- @ikigaibook
