Ever since the 1975/mid-80s/mid 90s Armagedon fiascos I've been serving God to the best of my very imperfect ability as if the end is coming today, but preparing myself secularly and otherwise as if I'll live over 100 years old and it'll never arrive in my life time.
Most JWs I know believe they'll see the end, but unfortunately we're all already dying one by one of old age and illness, and no end in sight.
Having said that, I've decided that the correct path to take in my case, and as it says in the Bible, is to worship and serve God because he so deserves it for his benevolence and his creation, not waiting for any so called "end".
