Listen, you absolute mess of a human being, you're going to need some motivation to get off the couch.
Here's some tips:
1. Get off the couch.
It's not that hard. Just stand up, walk over to the door, and push it open. Boom.
2. Eat a salad.
Don't @ me, but it's scientifically proven that vegetables are good for you. Ask your doctor, or Google, or the internet, or whatever.
3. Take a walk in the park.
It's not a park, but your backyard will do. The point is, get some fresh air, and don't die alone on your couch.
