A bad day doesn’t make or change your life any more than a good day does because the effect of a single day on our lives fluctuates. One day can make you feel stronger or wiser or better. The next moment or the next day can make you feel weak and drawn, even defeated. Things change. Don’t worry about it. Examine the situation because our attitude has a lot to do with how we see things. Stay focused and take the day as it comes. You're going to be just fine.
