Blood for success in the Hollow Network

You opened the door, kids, now you are the treat no more tricks, join Jack to pay back.

You farewell your soul, only relief nobody will miss. You are born, welcome to HN.

What would you sacrifice for success?

P.D: HNers, Thanks for the English learning advices on HN about "How do you write so well?", On Writing Well by Zinsser is a wonderful advice.
