This is such a tough one for me. There are so many inspiring people in the world, and I get inspired by them in different areas and aspects of my life. I can't choose just one person, it's impossible.
Family members, friends, acquaintances and even strangers on the street inspire me. Whenever I see someone with a physical disability, I get inspired to be more thankful that I can use all my limbs. Whenever I meet a person that has such a positive outlook on life, in spite of their circumstance, I feel inspired to be more grateful and change my outlook. When I see a person that has obviously gone through many hardships in their life, and still try to make the best of their situation, I am inspired to live the best life that I can. This list can go on and on.
I think everyone has something special and unique about them, and has the potential to be an inspiration to others. The best we can do is to live our lives in such a way that others will be inspired by us.
The bottom line is, I think anyone can be inspiring. Just open your eyes and look at the people in your daily life. They don't have to be a rocket scientist or a billionaire or a freedom fighter. Anyone that makes you want to be a better person, it doesn't matter in which area or aspect of your life, is an inspiration.
