Independence and goals. Someone that's making the most of life, and not satisfied with being a shift leader at mcdonalds or a team lead at walmart. Someone that has a heart for others, and is able to form their own opinions. They don't have to be a model, but the effort must be apparent; dont be a slob or unkempt. Be comfortable being silly.
Also.. being open minded about kinks and new experiences is a huge plus.
