According to Buddhism, hope is a poisoned purse. To continually live in hope is to make inadequate the present, and given that the present is the only thing we can be certain of, that's a half life. By definition life cannot get any better than the present moment, because the present moment is the only life we have.
As a theist of kinds I've seen just enough for me to allow for the possibility of an afterlife. So I live in the hope of one, you could say. But I try to live as though there isn't, because otherwise I'm missing the miracle of me, now.
