At the end of the day, one should be able to look back and see some progress towards a goal. If you have no goal, I suggest that you get one. Goals are measurable and it keeps once focused. As I look over my day, a lot had to be done and I still got to my goal. I started after 9 pm, but I did it. The time given each day can be wasted or used wisely.
Ecclesiastes 3:1 KJV To every thing there is a season, and a time to every purpose under the heaven.
