Good read yvonneb! I would agree that time management starts with our self.
I personally use my own simpler time management technique. I'd like to share it as it might help other people too.
Before the workday, I list all my priorities already. During work, I work on these priorities one by one. I never multitask because this is counter productive. I also use
this tool for management to monitor my work hours, reduce distractions and increase productivity.
At the end of the day, I will evaluate my performance for the day. This will help me improve for the next day.
This technique helped me a lot. I am sure it will help you too.
