My older sister is my role model. My family is hands down the most critical group of people I know. For as long as I know, she has done well for herself despite their constant judging; though she had her share of mistakes. She definitely taught me to not pay attention to what people say because what you do will not always please everyone.
I think everyone needs a role model. We do not have enough time in our lives to make every mistake possible and learn from them. Role models help you find solutions and preventions to problems big and small whether they are aware of their influence or not. Certainly makes life a little easier.
