Your smile is your logo, your personality is your business card, how you leave others feeling after an experience with you becomes your trademark.
Love and passion for your work, gives you a smile on your face. To give real service, you must add something which cannot be bought or measured with money, and that is sincerity and integrity. Let them feel better, stronger, more loved, valued, or anything they need what you can and will be able to give them with your profession.
Your energy introduces you before you even speak.
