Are you interested in whether it's grammatically correct or whether a native speaker would ever write it like that? I suspect there are different cultural sensibilities at play here. If you just want a correction; Family (or school) rules are not interesting but they are important. They help me develop good habits and grow into a healthy, helpful and useful person. How I might express a similar idea: Rules are not interesting but they are important. They provide a framework that allows us to develop good habits and become more successful people.

Rules help me to grow up as a healthy, helpful and useful person.'? Just Break the rules sometimes and have fun :)
