How? By asking for small commitments.
Instead of asking them to change all of their telephone lines to your long-distance service, why not ask them to change just one line?
Instead of asking them to try your entire skin care line, why not ask them to try just one product first?
Instead of asking them to try your nutritional package, why not ask them to try just one item first?
It is easier for prospects to make a small, trial commitment.
This gives you a chance to prove yourself, and to prove your products and services.
