There are many different kinds of people in this world. There are different races, genders, backgrounds, those with certain religions or beliefs, and many, many more. Along with all the obvious things, there are the people who have the ability to inspire you, or impact your life in one way or another. When we hear the word "inspire", usually we think about good things these people do that make you want to be like them. But there is much more to it than just that. Some of the things people do can be things that are evil or not right. This may also give you the inspiration to make a change in the way things are. They give you an idea of what things you decide you wouldn't want to have done in your life. For example, there are some people who believe abusing people is the only way to get your point across. You may think "I don't want that life for my family or friends". This thought can lead to you doing something about it, like starting an awareness page on Facebook, or setting up a neighborhood watch for things like this (that is, if you don't have one already). The thing that inspires you may not be this drastic, but regardless of the situation, you know what I'm talking about.
In my life, the things that inspire me most, are those who have been there for me through the good times and the bad. They have shown me how I can be a better friend, and how to make life better in general. I realized that there is always room for improvement, even if you think you are amazing at something, and that sometimes, criticism helps A TON. There is always something that we, as people, can change about our life and/or our ways of living. I have had people tell me that you have to have fun in life, or things won't be interesting. My grandpa, for example, is like a big kid; he starts food fights, water fights, and he teases all of us like we tease each other. He doesn't know it, but he is one person who has impacted my life for the better. He makes me want to be like the fun, crazy person he is. Just like my grandpa, some people don't even realize how much they impact someone, or if they even impact them at all.
My advice to you, would be to look for ways to make your life better. Allow for improvement and criticism, but don't let the criticism make you feel bad, or take over your life. And last, but not least, try to be the one inspiring others. Live your life in such a way, that people will look up to you and that they'll want to do the things you do. It's hard to do sometimes, but all it takes is repetition. :)
