Help yourself focus on the first important task in the morning by putting that task on your keyboard before you leave the office the day before.
This reminds you as soon as you arrive that it is the most important thing for you to do.
It helps you to focus on an important task first.
I think better first thing in the morning, so forcing myself to work on that most important task gives me a sense of accomplishment and satisfaction when I complete it.
How do you keep yourself focused?
