When I was about seven or eight years old, I once went into the barn（畜棚）one evening where my dad was doing his daily work. I was surprised to see him wearing his hat backwards. It looked funny.

When I asked Dad why he put his hat backwards, he smiled and gave me an explanation. There was a large water tank（水槽）for the cattle（牲口）that had to be filled every day. Since it took a long time to finish the work, he would turn the water on and then go about doing other things like cleaning the barn or feeding the cattle, which usually took him twenty minutes or even more time. The danger, of course, was that if he forgot to turn the water off, the tank would overflow and water would be wasted, which would make a mess.

Then he told me the reason why be had his hat turned around. When he finished other work and began to take off his work clothes, he would notice as he removed his hat that the visor（帽舌）was not where it was supposed to be. This would remind him that the water was still running. Then he would go back to the barn and turn it off.

I have seen my dad develop many other systems over the years. And I will never forget how helpful they are. Some may have even been life-saving. Now I’ve used a lot of them, such as putting my car keys in the same place every time.

Sometimes, people may forget some things. So they will easily make mistakes though they may try their best. Using some good methods can be practical, and as simple as a checklist. Once you stick to it, you can really benefit（受益）a lot from it.
