Correct my essay?

While lying in bed, I toss and turn; my mind wandering; my thoughts meandering; and eventually, I doze off. What keeps me up at night is not excitement over the holidays or tomorrow's big game, but rather a passion and a thirst for progress. Politics is a mundane field of study for a lot of people. Many of my friends can't stand the thought of having to discuss public policy and political culture. For me, however, its something I genuinely enjoy. 

It wasn't long ago that I, like them, misunderstood people's excitement about political events. I believe it was during the healthcare talks in 2009 that I first fell in love with the science of politics. Up until that point, I saw politics as being a game between old men in grey suits. Watching the public discourse on television and hearing people's personal testimonies forever changed my opinion. It isn't about power or the office; it's about people and the ability to change life for them. Regardless of which side of the aisle you're on, I believe we all have an innate longing for progress. 

Those arguments influenced my perception of a politician's importance and a political scientist's love. No matter the issue–environmental protection, food and drug regulations, or healthcare reform–politics is important to all of us. It touches something in everyone's life and even the most boring of subjects can have a huge impact on a person's career, health, and livelihood. My father is a pharmacist and small business owner; my mother has scoliosis. Whether its working in my dad's pharmacy or helping my mom with day-to-day activities, I've learned things you can't find in a textbook. I've seen the need for change and progress in more ways than one. 

All of this is why politics intrigues me so much. One vote on Capital Hill changes the lives of many. Whether is healthcare reform, economic policy, or something close to home like investments in schools and infrastructure, the science of politics is present in all of it.
