One of the most annoying personality traits can be tardiness. Being late is a very annoying personality trait as you will always leave your friends hanging and waiting for you to get there. It is important to keep your word and your promises and if you say that you will be there at a certain time, you are giving your word that you will show up at that time.
In order to help you not have this personality trait, make sure that you give yourself more than enough time. If you know it takes you an hour to get ready, make sure that you start getting ready an hour and a hlf earlier so you can make sure you will leave on time.
