Many investigators feel uneasy stating in public that the origin of life is a mystery, even though behind closed doors they admit they are baffled.
Darkness comes. In the middle of it, the future looks blank. The temptation to quit is huge. Don't. You are in good company... You will argue with yourself that there is no way forward. But with God, nothing is impossible. He has more ropes and ladders and tunnels out of pits than you can conceive. Wait. Pray without ceasing. Hope.
I think that life is difficult. People have challenges. Family members get sick, people get older, you don't always get the job or the promotion that you want. You have conflicts in your life. And really, life is about your resilience and your ability to go through your life and all of the ups and downs with a positive attitude.
