Came here to say this. If you have anyone in your life who would be willing to keep you accountable by being your hiking buddy, that helps me a lot. Before my partner and I got together, she was my friend who liked hiking and got tips from a Facebook group on good locations. Every weekend, she had picked a place for us to go. Since I didn't want to let her down, I got my ass out the door. I never regretted a single hike because they were all to great nature spots.
I realize this is limited by geography. I'm lucky to live in a place with a lot of great trails. I used to live in a place that was flat and uninteresting, so this depends on having access to nice trails.
