A business mission statement accomplishes many things, including attracting the right customers for you, setting a goal for yourself, and giving your employees a focus statement to aspire to and believe in. You should memorize your mission statement, and have your employees, if you have them, memorize your business statement. It is, after all, what you are all about and what you strive for. Customers will be attracted to you via your mission statement, so if you have a statement that fits you perfectly, you will have customers that fit you perfectly, seeking the same values and ideals.
Like attracts like, as described in the law of attractions (LOA), and you will benefit from having a mission statement that is clear, decisive, and appealing to the group of customers you are looking to attract.
Not to mention that once you have a mission statement, you can draw new customers looking for certain values and goals.
In the photography business, this is especially important. There are thousands of photographers out there, so what makes a customer choose you over the other options? Your mission statement, which involves your values, your goals, and your personal care. Make it clear to your customers why you are in the business in the first place, what you are trying to do, and why they should be a part of it. If you do that, and do it clearly, you will find that people seekn you out. Never underestimate the power of a strong mission statement.
Remember that you are a photographer. You have your own ideas, perspectives, and visions. Include them in your mission statement and make yourself, and your business, stand out.
