The most important things to a person is their name and their birthday.
Remember both and you’ve nailed a strong relationship for a lifetime.
When you meet someone for the first time make an active effort to remember their name.
It helps to attach some form of physical story, as this can act as a simple link of memories.
Secondly, if their birthday is mentioned take a strong mental note.
Once the conversation as definitely concluded, save it straight into your calendar or notes to make certain you never forget it.
