One thing that modern civilization has tried to eliminate is failure. Mostly failure in our kids lives, but that is a huge detriment. 
Some people even have the fear of failure, and this leaves them paralyzed and as a result they do nothing. In life no decision is worse than the wrong decision, but that is another topic. Failure is in our nature, just as I observe my daughter failing to lift and crawl during tummy time. If I would go to her evertime she cried, she would be a life long baby, and trust me as a dad, I want to run to help her every time she cries. But I can't, she must overcome herself. My parents let me fail all the time, and at the time it mad me mad, but I also learned many valuable lessons. In fact, I have learned most things by my failures, obviously I am not talking about putting your kids in life threatening danger, but if you play with matches and get burned, you know they are hot. If you cut yourself on a knife, you learn that side is sharp. I teach my guys how to do drywall patches by failure. I let them watch me, and then I have them do it. Of course I have them start out on small patches, but I let them struggle and try and figure it out, then I show them how to fix it if it needs to be fixed. But I let them fail first, then wait for them to ask for help. We do more harm by trying to make life perfect, because lets all face it. It is not perfect, and when your gone what will they do.
