I feel like some of my best years have been since Trump got elected but they have nothing to do with anything Trump did (he's been terrible). It was mostly because I was confused as to what to do, so I felt that no matter what happened in Washington or throughout the nation or how bad it got, I needed to focus on me and making sure I was at my best. And when I see people protesting Republican health care ideas, people fighting for women, people fighting for the environment, people getting organized for gun reform, I'm always reminded that many people will get off their ass to do the right thing. Things may have to get way worse before they get better (a conversation I've had with a few people from outside the US who are fascinated by current events here), but I firmly believe they will, even though it'll take time and a hell of a lot of work.
That's helped tremendously and I hope to follow this mindset when Trump is gone, be it 2021 or 2025. It's the healthiest thing you can do. Obviously, everyone has different circumstances, and even for me (my life's never really been bad), it took a while after the election to really get into gear and feel like I could turn things around and make 2017 a very happy year and a year of firsts. But it's worth the effort.
