My greatest motivator is my fiancee. He gets me out for hiking every weekend and pushes me to try more difficult trails. He's started exercising with me and it helps so much.
My biggest saboteur... My fiancee. He looves candy and greay food and going out to fancy restaurants. He likes going out on date nights. Which is okay, because I know what the right choices are. But once we get to a restaurant and I try to make sure I order the right thing he gives me the "it's okay, you've worked so hard!" Or "we have that big hike tomorrow anyway" and I cave. Which is my own choice but he makes it so easy for me to justify it.
He's super supportive though, and he doesn't do it on purpose.
I just need to stay strong!
