Easy Does It. For Sustainers, success is alright, I guess-as long as it's accomplished in relative comfort.

Michelle Paster's education business has no debt, morecustomers than it can handle and a hands-on owner whose concern forquality requires her to do virtually everything herself.

"I strongly believe that working with kids who havelearning difficulties makes a tremendous impact on theirlives," says the 29-year-old former teacher.

To make an impact on as many kids as possible, Paster left herjob with the public schools to start LearningWorks Inc. in NewtonCentre, Massachusetts, last August. Now she devotes herself fulltime to teaching, training and consulting students, teachers,school districts and parents on the subject of kids with learningdifficulties. "It's very rewarding," Paster says ofher work. "And when you're successful with a kid, it'sa great feeling."
