What makes YOUR life meaningful?
For different people there are different things that makes their lives worth living. For some it might be some kind of passion, a hobby, etc.
Some merely carry on living out of fear of death. Some don't know why they even get up in the morning. Others have never thought about it.
Why do you see it meaningful to get up in the morning? For me personally, it is the sheer mystery of life: before I die I want to find out what we are, what exitence is all about and why everything is the way it is. I want to examine life, as Socrates said the unexamined life is not worth living.
