Life is full of work. You may be a student going to school, or a parent managing a household, or a you might be a worker in an office or a factory. Any way you look at it, there you are . . working.
One way to make today a good day it to have a reason for working and to remember that reason as you go through your day.
Making money is almost never the reason for working. If you are a student, you might be going to school because you love learning. If you are a homemaker you might be working to have a place that makes you and your family comfortable. If you are a worker outside the home, maybe you have that dream vacation on the horizon or the you want to be able to buy that new patio set.
Having a good day isn't always about what you are doing today. It can be about doing something today for tomorrow. Spend some time today focused on the *why* you are working . . and make today a good day.
