fire isnt lost you cockbreath, it s just redirected toward raising life, while you ll focus on your "achievements" until you reach your 50 s, will be alone and nobody will give a fuck about you just like you never gave a fuck about them. Also most people actually have enough "fire" to share between differents things and not just kids and couple, why arent you able to do so ?
Is "raising life" some kind of the greatest thing ever..?
And once again - why are you so afraid of being alone? You are a smart person, and intelligent people won't ever be alone in this day and age, unless they choose it.
Not having a family doesn't mean one can't contribute or be a generally good/well doing person to others. You have some kind of very skewed extremistic outlook on these issues. That's not healthy. One day you'll miss the forest for the trees due to that kind of thinking, than sit on your ass and think "Well maybe holly book hasn't had all the answers afterall." (it's usualy a very tough realization for a deeply religious person. I've witnessed that personally.).
