If, you are Mindful, aware, attentive, have direction, treat her with care and consideration. Engage her mind and sense of responsibility with small noble thoughts, such as, “Oh, lets see how peaceful your room feels like today. Maybe I like to visit your room. That depends on how many trash are in your trash basket instead of on the floor. Lets check it out.” Letting her count the trash on the floor versus in the trash basket in her room and decide for herself how it feels to be there, then she becomes filled with purpose. Motivated to make her room inviting and peaceful, she gets on it. Putting things where they belong and looking under the bed for more trash to show you that she cares as much as you care. This not only makes her feel important, she feels peaceful and her sense of learning, practicing best methods for a happier life is encouraged and strengthened.
I find that this works well with adults as well. Even with oneself. We just have to take time for it and not assume that adults, including oneself, know or should know everything and do not need encouragement or guidance. When you sit to meditate or practice Mindfulness in daily life, there is an important practice that needs to be understood as well, and that is Clear Comprehension.
