As noted elsewhere, wisdom is the greatest blessing in life. Wisdom implies a high enough degree of spiritual development to isolate the self from most of the vicissitudes of the world of matter and to commit suicide when bodily pain impinges excessively. Failure to commit suicide when the going gets tough is prima facie evidence of lack of wisdom. Alternately stated, to be unwilling to let go of a life that offers little more than suffering is prima facie evidence of folly. (Again, we are assuming that wisdom comprises both understanding and self-discipline—failure to commit suicide likely indicates lack of self-discipline rather than lack of understanding. There's also the case of highly disciplined yogi/martyr types who can smile and be happy while being tortured to death, and hence don't need to commit suicide to prove wisdom. I'm assuming most of us aren't at that high level of spiritual development.)
