You must accept that you might fail; then, if you do your best and still don't win, at least you can be satisfied that you've tried. If you don't accept failure as a possibility, you don't set high goals, you don't branch out, you don't try - you don't take the risk.
We have an obligation to live in harmony with creation, with our capital... with God's creation. And we need to administer and work that very carefully.
