I never truly believed it personally and never really liked talking about it for that reason. It was this thing I grew up hearing but couldn't be fully invested in so I rarely thought about the future. I always thought it would be far more likely that I would live out my life and die of old age and (hopefully) be resurrected when everything was over. To be honest, that's what I hoped for because the thought of living through Armageddon/the great tribulation really terrified me.
My dad was/is definitely a believer and would always tell me that "this system probably won't be around by the time you finish school." I even had an elder say "we never thought you guys would get this old in this system." Well, I graduated a decade ago and it's still here.
