All the time. It's a scary thought and anyone who tells you it's not is lying. Leaving a legacy, making a name is all well and good but the thought of simply not existing, absolute nothingness is scary. Lately for me however I think I've squandered the gift of life so to speak. Made some bad decisions, in trouble financially, emotionally drained and just feeling defeated I think I'd be better off not existing. Thought about suicide but then whatever debt I have gets passed to my family and I couldn't do that to them. It would mean I've only brought them grief in life and in my passing. Make a long post short, yes I think about it more often than I'd like.
