There is a series done by John MacArthur on self-discipline and it is well worth the listen. It's a four part series you can find here. I recommend you listen to it if you're at all interested in developing your self-discipline. It's important to realize that God made us creatures of habit and when our habits are good, that works for us. Conversely, when we have bad habits, it works against us. Come on, join me as I work toward some self-discipline.
Thought for today: Self-discipline doesn't happen without effort. You have to get up, brush yourself off and get going. Make today the day to get started in a small way and eventually the big things will take care of themselves.
