When public speaking， pause frequently. Pause before you say something in a new way， pause after you have said something you believe is important， and pause as a relief to let listeners absorb details.

质量从来不是偶然的，而是意图和努力的结果。

You want to be extra rigorous about making the best possible thing you can.

The question I ask myself like almost every day is, 'Am I doing the most important thing I could be doing?'
