As Salamu Alaykoum dear brothers and sisters!
Being an older sister to three siblings is truly a blessing, yet very challenging as I am meant to fulfill the role of a "perfect role model". Perfection is an imaginary term, it is nonexistent in mundane reality.
I very much doubt the idea that I can be the "perfect role model" to my siblings. I strive to set a good example for them whilst nourishing their minds with beautiful thoughts and knowledge. We are all role models to one individual or another. Therefore, we carry the great joy of developing and nurturing the beauty of Islam within the individual(s).
A role model is an open minded soul, who plants the seed of divine love in his brother or sister.
