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.
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.
After using this, remembering names becomes that much easier. Use names with everyone you interact with, practice this and make it a habit.
