אל תצר צרת מחר כי לא תדע מה ילד יום שמא מחר בא ואיננו נמצא מצטער על העולם שאין שלו
מנע רבים מתוך ביתך ולא הכל תביא ביתך רבים יהיו דורשי שלומך גלה
The Gemara quotes additional statements from the book of Ben Sira: Do not suffer from tomorrow’s trouble, that is, do not worry about problems that might arise in the future, as you do not know what a day will bring. Perhaps when tomorrow comes, the individual who was so worried will not be among the living, and he was consequently upset over a world that is not his.
Prevent a (public) crowd from inside your house, do not let many people enter, and do not even bring all your friends into your house. Make sure, however, that a crowd seeks your welfare, and that you have many allies.
In case you need it: "The Talmud teaches: “The Sages taught, if there is plague in the city, gather your feet – i.e.-limit the time you spend out of the house, as it is stated in the verse: And none of you shall go out of the opening of his house until the morning.’ And it says in another verse: ‘Come, my people, enter into your chambers and shut your doors behind you; hide yourself for a little moment until the anger has passed by (Isaiah 26:20)”

One must try to transcend one's individual world. Sometimes self-centeredness fills one's whole being, until all of one's thoghts are focused only one's own individual concerns. This way of thinking undermines a person's greatness and will eventually lead to both physical and spiritual suffering.
Instead, one must dedicate one's thoughts and desires to the greater good: others, the people, and the entire world. And (paradoxically) through doing this, one will come to know one's own essence.
