Probably, today is a bad day. But, When that, I canescape from being bad. The way is to stay calm, only. For example, if you have a mistake to change the train, I question myself to confirm the direction before changing the train. When that, I can notice what I didn’t that. So, it is too simple. It isn’t a bad day, I forgot to confirm the correct directions. It’s the only thing, I think.
