Personally I'm not a religious/spiritual personally I don't see how it can be real but that's just my personal experiences and my way of thinking. But if being spiritual makes you happy then 100% you should be spiritual but it's not necessary if happiness is the only thing you're looking for.

Yes

Of course that's the way of life
