Because it's not my time yet.
I don't know what else they expect us to say here. I suppose that if someone had considered taking their own life, they could write something better than I have to contribute to today's topic.
So, with that, I'm going to say, I haven't completed my life's work yet. I still have something, or somethings, to do in this world.
I don't know what it is, exactly, yet.
But you can bet I'm going to figure it out and do it!
