Repetition
Repeat the person’s name as many times as possible in conversation. Use it when it is appropriate. Use it when you are saying goodbye to that person. Afterward, repeat it in your head as much as possible.
Association
Make associations of physical characteristics, names of landmarks, objects, buildings, companies, etc. Use color nouns and similar words to help you remember the name. We as humans remember things better in pictures.
