I think the main thing you should change is your attitude. Look we all have to do things we don’t like/are boring. This is life. But you won’t get as far with your big ideas if you don’t realize you have to do boring things. Like wanting to change the world. You know how most people get it done?
By connections and money. Networking bores me to tears but I still do it because the museum I work at needs donors and people who want to come. We also have to write grants which is pretty dry. But we still do it because that’s how we get money to go on digging trips and field trips for little kids. I may not change the world but I get a kid interested in science and they may change the world.
You will most likely ignore me since I’m one of those people who are happy with the “average american life” and that’s ok with me. But you want to go into a field that requires you to work with a lot of people and a lot of boring details. Some of my friends are in the same field that you want to be in. They don’t get to be a superhero, their jobs are pretty boring at times. That’s what they tell me.
But those grades will follow you because universities and colleges require all transcripts from where you attended school. If you don’t provide them, they could kick you out or maybe sue you if they gave you money. My advice is retake those classes you didn’t do so well in. Then withdraw and go to school online. After you gain all the credits you need apply to the main branch and maybe some other schools. William and Mary, George Mason, American University, and George Washington University are all good but pricey schools for political science.
