Take care of the important things:

Making sure you know where you are going these days is very important. Make sure you have spoken with the client and booked any initial appointments via telephone.

Make sure the address exists, you have somewhere to park or the address is easily accessible and that someone you trust knows where you are, and what time you are expected back. Some clients are happy to pay traveling expenses if it's awkward to reach them. It is always worth making a call to a friend before you enter a new customers address and call them again when you finish.

Taking simple steps to respect both you and your clients privacy is essential.

The vast majority of new clients are very welcoming and you'll have a new friend for life as long as both parties are respectful and understand what's expected of them.

Clearly explain what is going to happen prior to making appointment arrangements.

Have fun and enjoy it!
