This is a tough topic to approach. You are in business and you want to be available whenever one of your customers need you, right? WRONG! They will wear you out and quite possibly take you to an early grave if you are not careful. You want to live your dream by serving your purpose here on Earth, but isn't happiness apart of that? If you, have to think about the answer to that question then you need to keep reading.
You are in a business which has allowed you to make money with what you were born to do. Unfortunately, knowing proper boundaries has not been a strong suit if you find that you dread customer interaction. Of course, the first 100 times I encountered the gnawing feeling of "oh no, not that client again", it was hard to put my foot down and mean it. It was not only hard for me to put my foot down, but it was also scary to turn away money. At least I thought it was money, it turned out to be a freaking headache. After not saying no when I should have, I dealt with regrets about not saying no. I dealt with the struggle to get the customer to understand I really did have office hours. I struggled with not being readily available for fear someone else would get my clients.
The truth is no matter if you have one person or 100 people wanting your service you would benefit from having boundaries. You would benefit by making yourself follow the guidelines of a real business owner. Striving to punch in and out on time will not only allow you to keep your sanity, but you will discover when you really need it that your customers will know when you are open for business. Strive to be the best at what you do and people will wait to do business with only you.
