When starting a goal, it is exciting to be in the beginning phase because you have drive, excitement and ambitions to get started. As time goes and the weeks turn into months, you no longer feel the same way as you did in the beginning. You start skipping days on working toward goals, then you slow down the progress even further, and you eventually stop.
You have to believe it before you see it and keep push even when you do not feel like it. Focus on the finish line so you not only see who you are becoming, but be proud of yourself for completing what you said you would do.
The old saying is "Keep your eyes on the prize". Listen to the weeks episode to get some encouragement.
You come to far to start back over, so keep pushing!
