When you are alive you can work for the welfare of humanity, you can help every one around you. And you can donate your body parts in case of some accidental deaths or even after death you can donate your body to some medical institutions so the future generation will learn how to help others and the needy one.
There's too much I haven't done and too many places I haven't been yet! Too many people I haven't met and too many cats and dogs I haven't petted! Haven't been there/haven't done that! Oops, gotta go! See ya!
First, everyday we wake up is a blessing, life is so precious. Maybe you need to take a trip to the hospital, visit the children's wing in the hospital where they treat cancer, only then will you understand just how lucky you are to be able to endure another day if life.
I'm with theZ on this one. This is fun. I don't really see any reason to not enjoy life and I'm far from the mental disorders and delusions I had as a child so I rarely can't think of a way to be happy. I get a big kick out of beating down the forces that would bring us all real suffering. I'm working to make earth a desirable planet to live for all my little alien brothers and sisters. The more the downers down it makes no difference to my static progress towards bringing humanity into enlightenment. We will be free from delusions if I have to die to make it happen and no one will stop me from slaying the dragons in my life except death, something I'm actively avoiding.
I know there's nothing left afterwards, so it wouldn't make much sense to throw it away. Unlike theZ and Truth, my desire to live does not stem from seeing life as a chance to have fun and live to the fullest; I live life waiting for the next challenge. I see life as a challenge to overcome while making the most the most of it. When faced with a challenge, I take it on and don't back down. Whether I beat it or it beats me, I remain standing and scoff at life "Whadd'ya have for me next?" And life give me challenge after challenge and I take them on laughing and having a good time with it. Life and I will repeat this process till the end when death arrives to spoil our fun. And when death does come? I'll obviously try and postpone it, but I cannot do that forever-- no one can. That's fine, for when death arrives I will go with no remorse, no regrets. Plus ticking people off and being annoying, I like those parts of life too.
