When working in a service oriented setting, you usually spend most of your time talking business with your clients. While business is always important, you should make sure you also take the time to learn about your clients' personal life as well. Asking about your client's children or favorite hobby allows you to connect on a more personal level, which can result in a better professional relationship. It is also a good idea to recognize your clients' birthday because it provides you with another opportunity to connect with them.
To make sure you remember everyone's birthday, create a separate client calendar to keep track of these important dates. Also, remember to send a business birthday card a few days early so it arrives on or before the actual birthday. This will show your clients that you are both thoughtful and organized, which are two great traits to showcase in a business environment.
