There are a lot of important people in your life. Of course, you are not responsible for the well being of all of them, but you can take it upon yourself to look out for them. This is not to make sure you have friends that will look after you when you need their help. Friendhip and love are not simply matters of give and take. Sometimes, you just give without any benefit for yourself. Althouhg looking out for people you care about does have an intrinsic benefit. It will give you a sense of belonging and togetherness that nothing else will.
