Great suggestions! Definitely have a response when you hear "no, not at this time" after asking about those potential friends and family members, coworkers in similar situations, etc. Planting the seed may make a difference and it's about the value in the service you will provide that "future" referral/prospect. For example, you may say something like, "I find that when my students are in their programs, wearing their t-shirts, talking about their amazing experiences, they influence others who become excited to learn more! It's been a pleasure to work with you. Please share my specific information and I will gladly, personally follow up right away with anyone you inspire the same!" Pay it forward; make a difference!
