I'll be dead by the end of the decade
Why would you say something like that?
When I'm dead, my soul will be free and I can go anywhere.
You should not predict your own death. You should try and find things to live for now.
I'm not concerned with that shit.
It can be good to not worry about death but you do have responsibilities now, and people who care about you. It can hurt your loved ones when they hear you talk about how you are anticipating dying soon.
