Many of us are familiar with the saying "First impressions last." This pertains to how we regard our first look or experience of something or someplace, or our first meeting with someone. Such first impressions give us a feel of whether something will go well or if someone is worth the acquaintance. This concept extends to place like airports, which are regarded as gateways to countries or cities. International airports provide a first impression for a country among foreign visitors, which is why such gateways need to be among the best infrastructure in a country.
There seems to be not so many references about last impressions. However, I believe these are also important. This belief comes from another saying, which I first heard from one of our English teachers in high school. Our freshman English teacher shared with us that "you are only as good as your last performance." I think she was encouraging us to do our best or be at our best every time. Later, I would have experiences that make me remember this saying. How many times have we done our best, foul up one time, and then basically be remembered for that fumble? It will take another good performance to recover, at least partly, from that debacle. In some cases, it takes long before memories of that one time is forgotten or recalled lightly. Do your best every time and be careful not to lower your guard against mediocrity and stupidity. Such carelessness may lead to something you don't want yourself to be involved in and remembered for.
