Why do we want to give presentations?
Reasons:
Obligation for publication
Real reasons:
Opportunity to advertise your work
Obligation for job report
Obligation for work review
Obligation for communication
Opportunity to demonstrate yourself
Opportunity to improve self-understanding
Opportunity to influence others
Every presentation creates an opportunity for self-advancement!

What a presentation is about?
Motivation:
What the problem is.
The truth is:
Why is the problem worth researching?
Justification:
What the approach is. Why is your approach the best possible?
Reward:
What the solution is. Why is the solution generalizable or limited?
Public want to know what; intellectuals need to know why.
