David's speech mentioned about time management.
Actually, he quoted from someone "time management is a misnomer".
Why? Because you cannot do anything about time, all you can do is manage yourself.
So how can we manage outself?
To higher the efficiency to do something need concentration, but many times we're interupted by e-mail, msn, etc.
So maybe I should start to schedule for my daily time block, and manage myself first.
I should put the knowledge into practice, from tomorrow.
