There are times for each one of us when we feel unmotivated, uninspired, and un_______. Please don't feel like you are a failure or that you have failed just because you are facing these feelings. Healthy living is not void of not wanting to make the "right choice". It's about making one decision at a time, and making sure that the majority of those decisions nourish who you are.
The blank space is there for a reason. Let it run its course. BUT, don't let it make you think it's the end of yours. Think of it as a chance to find new motivations and inspirations! Get excited about life! You only get one! Don't let it down!
