How can I find a balance
with my time limit?

How can I fill the time limit? /
How can I fit so much content?
- 30 min, 45 min, or 1 hour may sound like a lot... But when you are on stage,
it will fly by - Always leave time for Q&A! (Recommended)

- Define key terminologies
- Don't assume!
- Clear & logical structure

How can I not bore the audience?
- Ask yes/no questions

e.g. mentimeter - Less text-heavy slides

First impression matters...
"You only have seven seconds to make a first impression" - Carol Goman
- It starts as soon as you enter the stage
- Be confident when you walk in
- Make a conscious effort to smile

When on stage...
- Take pauses
- Make eye contact
- Slow and steady pace
