One does not need a reason to live. You're already here. That's making up a reason after the fact. You don't have to will yourself into existence. These are category errors, or mixing up language games. Similarly, there is no meaning of life in general. Meaning is for books, discussion, family, social life. It in no way applies to life in general. We can only be confused if we think that way. You may need meaning and reason to act, or, more likely, you may think you need it. We want one guiding principle for action. The truth is that life if various. You never know what's going to happen, and you never know what you are going to do. Meaning for action has limited application. It does not apply to life overall. So when you have the itch for meaning, find out what it is that is missing in your life in which you should normally be engaged. Most likely, our social connections are insufficient from what our genes and culture urge. We are disconnected from family and co-workers, we are trying to be a machine that just goes to work and makes money. So we lack meaning in social life, because we don't have a social life. When you have the itch for meaning, apply it to something locally, not to life in general.
