Stage 1: Divide your social circle into an inner circle (friends, family, colleagues) and an outer circle (old friends, distant relatives, ex-colleagues, etc.).
Stage 2: Reach out to your inner social circle first – friends, family and colleagues. They are most likely to give because, well, they love you, and because they can feel your passion for the cause.
Stage 3: Reach out to your outer circle next – old friends, distant relatives, ex-colleagues, etc. When they see you've already got supporters giving to your fundraiser, it will make them want to join in as well.
Don't stop reaching out to the people in your network. Create a ripple effect
