I have no huge problem with others having it, it just ain't for me. I lost a need for questioning the afterlife, after a pretty depressing episode of life, and I don't only feel non-depressed, but absolutely fantastic. Free from many more social pressures than others in my life. Not totally, I don't think that's possible for me, but I still feel immensly liberated. An ego is a strangling thing.
Life is a leraning experience, yes.
Spiritual development is something I think only time can ultimately tell for a person. I can spend my life researching basics, or I can build upon or knock down the ideas of others. Or even make my own that fit in with some credubility. Or, I can bum about my whole life. I don't like the idea of not fulfilling my potential, as I believe I have a bit to offer.
