I recently turned 52. How did I make it so far? I promised myself when I was 20 that I would do my best to wait till after both my parents (but especially my mother) were dead before I ctb. Also, there was always the fear that I might end up in Hell -- or at least have a prolonged sojourn in Purgatory -- if I ctb. I have lived my life as if I were going to ctb one day, not fully committing to life (or to death, for that matter). I have never married, never had kids, never had any serious romantic relationships -- all in order to avoid devastating other people in the event of my demise.
A consistent routine (not just of prayer, but that helps a lot) keeps me alive. Also my ambition to be a published author is a major reason why I have not yet ctb.
Your mileage may vary, of course
