Seth Godin reports on his blog that actions are contagious. Whether it’s obesity, suicide or wealth, your chances of achieving those or any other milestone increases greatly when you hang out with others who are cultivating those habits. According to Seth:
The most important thing you can do is choose who you’re hanging out with. The second high-leverage thing is to put dynamics in place that reinforce the ideas you’d like to see spread. Celebrate the heroes. Make it easy for those ideas to spread…
Remember, people you do business with will "spread the word" about your goods or services with those whom they hang around. It’s not just health habits that are contagious…. it’s business habits and shopping habits as well.
Which is why Niche Marketing is SUCH a highly touted marketing tactic. Because just like diet and exercise, others are watching our choices and are prone to "fall in line". So, every customer you reach in effect is a tool through which to reach other customers, customers who are very similar in nature.
By tightly targeting your message, you’ll find it’s easier to speak to these tightly targeted customers.
