I've adopted a new motto, and it gets me through almost every workout. This saying goes beyond a physical motivation, it stems into my spiritual life as well.
"I want to be better than I am. I want to be different than the person I have become."
I've become lazy spiritually and I don't like it one bit!!! I could come up with every excuse in the book for it, but it simply comes down to my own laziness. But when I wake up in the morning and I remember "I want to be better than I am" it gives me that boost I need to get out of bed, and spend time with God.
Maybe we all need to aspire to be better, to be different than we are. Maybe we just need to stop being content with who we are...
