“We have no grounds for self-admiration, as though we were surrounded by our own possessions; they have been loaned to us. We may use and enjoy them, but the one who allotted his gift decides how long we are to be tenants; our duty is to keep ready the gifts we have been given for an indefinite time and to return them when called upon, making no complaint: it is a sorry debtor who abuses his creditor.” – Seneca
