It is necessary for your life to have a purpose, which means that you need to feel that your life has a purpose, a meaning and is powerful.
The purpose does not necessarily have to be external, in fact, just the condition that you have inside is enough, but this condition must be absolute.
Many people live their life with no sense of purpose at all, and this makes them feel like with no sense or meaning. They feel that their life is not going anywhere.
Here again, it is necessary to make clear that we are talking about inner intent and not external goals. Externally one may have or may not have a goal, this is irrelevant, but the sense of purpose is important. It is something that usually people confuse.
