All life is a chance.
The man who goes the furthest is generally the one who is willing to do and dare. The 'sure thing' boat never gets far from shore. There is a Chinese story of a farmer who used an old horse to till his fields. A week later, the horse returned with a herd of horses from the hills and this time the neighbors congratulated the farmer on his good luck. Then, when the farmer's son was attempting to tame one of the wild horses, he fell off its back and broke his leg.
