Maybe you've already done this challenge (I'm new to the site). But, I need HELP quitting the diet soda roller coaster. Maybe this could be a next challenge down the line?
For me ... I dug out an old picture of myself when I was in my best shape. I took a picture of it with my phone and use it as my background. Everyday I see that picture it reminds me of what I can achieve because I'm not looking at some stranger who does God knows what to get in shape, I'm looking at myself and it motivates me. I always take a few minutes before actually getting out of bed and mentally planning my workout into my day. What time am I actually going to get my workout in? I make it a priority. It works for me. Maybe it'll help you.
