Better Than Yesterday

I was asked by a client, who owns a gym, to create some vertical art that he could use as a back tag on shirts or down the leg of workout shorts. He likes clean modern, and wants to keep it simple one or two colors. The messaging was to read "Better Than Yesterday", and I had an idea, lets try it as an acronym. My thought was to see if we could make it a mantra, BTY, something you could see from across the gym or out in the world and it would remind you, BTY, be Better Than Yesterday.
These are my initial ideas. What do you think?
