how to remember names

1) Commit
Begin by making a commitment, like a conscious decision to remember people's names.

2) Concentrate 

Listen to the person's name. If you miss it or find a few seconds later that you’ve already forgotten it, and apologize for that and tell them if they can say their name again.

3) Repeat
You can already use the name immediately. Comment on the name if possible. And use it occasionally in the conversation without overdoing it.
