Being short most often refers to having a head that is close to your feet when you are standing up. Those who are officially "little people" may have a condition of dwarfism. "He was quite short with me" usually means he spoke to me in brief utterances, without a smile and in an unpleasant, gruff, grouchy tone. I am somewhat lacking in height. I used to be 5 feet 5 inches but now I have shrunk to only 5'3".
I gather that having a good height is expected of a man. Women may feel better when looking up at a man than being eye-level with him or looking down. Both sexes have a certain awe of a man who is tall. I have heard of Napoleon being short and maybe being sensitive about his height. I remember hearing that the Philippine ambassador was asked about his feelings of dining with a group of tall Texans. He said,"I felt like a dime (10 cents) among nickels (larger coins worth 5 cents)."
But short messages, often referred to as having "brevity", have important advantages. These days, not just 20 year olds but also increasing numbers of 40, 60 and 80 year olds, have their smartphones at the ready. At any moment, a call might come in. So, if you are going to ask for a favor, state your request in a short, direct form before you lose the attention of your requestee.
It may be that word choice, labels, terms are more carefully examined in advertisements and in political messages than anywhere else but I personally reserve very careful and ruminative examination of words for my picture of "poetry". Generally, poems are short, not the length of essays or reports or whole books. You may have heard that the current US president practices creating short messages called Tweets on social software call Tweeter.
Both Tweeter and the famous Facebook are now full of pictures, which can be considered a brief but powerful way of communicating. These days, we have "shorteners", special computer programs used for hosting quite long web addresses and substituting shortened versions of them. I can take a long web address, like this one

One of the most famous people for getting short is the American comedian known as Father Guido Sarducci (a.k.a. Don Novello). He is famous for condensing four years of college into 4 minutes by speaking important words for various subjects, such as "supply and demand" from economics.
These days it pays to get short.
