At my internship we've been struggling to get results on a particular experiment we've been conducting where we monitor the birth, proliferation, and migration of cells/neurons in the spinal chord. It has been quite a struggle for just over four weeks now. (Research in general can be somewhat discouraging at times - they say it has a 90% failure rate). I think failure is common when we aspire to do new great things and these failures cause me to question when optimism begins to be foolish, pessimism begins to be disheartening, and realism really lies.

In regards to failure, Thomas Edison is known to have said, "I am not discouraged, because every wrong attempt discarded is another step forward." Mustard seeds are tiny(1-2mm in diameter) but grow remarkably fast up to 9 feet tall. Would it be foolish of this mustard seed to say, "next season I'll be 9ft tall!"? I imagine it would be realistic...
Jesus, the greatest teacher of all time, performed the greatest of miracles known to man and performed them often. His disciples were often optimistic at the idea of them too performing these miracles - after all their Master, "gave them power against unclean spirits, to cast them out, and to heal all manner of sickness and all manner of disease." I suppose this optimism could have easily been harassed on many occasions, like when they could not heal a boy of his mental disease.
"I brought him to thy disciples, and they could not cure him," were the words of the boy's father to Jesus. These were the words of Jesus to the disciples in regards to why they could not heal him, "Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you." He also called the people present "faithless and perverse". To me it seems that Jesus teaches that we are often not optimistic enough. Perhaps, if the disciple had more faith and confidence the people, the father, and the boy would have had faith sufficient for the healing to take place.
It seems to me that optimism is realism when we really believe. Christ also said this to the people of ancient america, "And whatsoever ye shall ask the Father in my name, which is right, believing that ye shall receive, behold it shall be given unto you." To all the King of Kings extends the invitation, "Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you."
This is my conclusion: Pessimism is realism when we simply don't have enough faith and belief to be optimists. Optimism is realism only when simply do have enough faith and belief to be optimists. And realism is only what we really believe, which needs be in accordance with God's will.
Today, the experiment I mentioned earlier worked. Now I just need to keep on believing.
