Actually I just counted and amazingly I had 8-8-8-8-7 without even trying. I have now changed the first word of the last line from hope to hoping and made each line eight syllables (assuming I counted right). So this is a good poem in my mind: consistent syllable count, acrostic, and a nice rhyming pattern.
Does the next world really exist
Everyone thinks they will persist
And if it is a better place
Then let's go now and end this race
Hoping to see your smiling face
