I saw this today and it really was something I needed to hear. So maybe it will be helpful for you to hear as well.
Every guilt-driven "yes" means a "no" to something important in my life.
For example: A "yes" to a committee means a "no" to a night home with my kids. A "yes" to preparing for a event means a "no" to a good nights sleep the night before.
So, think about the "yes" answers in your life and what "no" answers will come from it.
