You are in a bad mood. It lasts all day. You think, it’s not a big deal it’s just temporary. The thing to keep in mind is that every person you came in contact with while in that bad mood sees that as your regular state. The first and possible last impression a person gets is during that time period so while you might think “it’s only temporary, no big deal” to others, it’s their permanent perception.
The same is true for a retail store. You walk into a retail store and there are boxes all over the place and it’s a complete mess, you probably aren’t going to return. The store employees might be thinking “it’s only a temporary mess while we make the store look even better” but for you, your opinion is formed.
Realize that your temporary is another persons permanent.
It’s a different way to look at things but one that can help you understand how people get the impression of you that they do.
Have a great day!
