12 January: Numbers as a language
The year 2010 written in the Roman system would be MMX. 2010 is "2 thousand and 10", therefore MM (2000) + X (10) = 2010 / MMX.

Communication
- If we do not have communication, we will not be able to interact with other people and humans will become isolated, and therefore will lead to the extinction of humans.
- Personally, I like ‘writing’ forms of communication, such as SMS, letters, etc… Basically because I feel that writing is more direct and to the point.
- It depends on the urgency of the situation.
- Some people say before they think. So I have to not take it seriously.

#2 Team Building Challenge - Debrief (II) Personal Reflection
Excellence is the quality of being good, so SST wants us to do our best at everything. I do not really have a specific talent that can help me to achieve excellence, but I think that by maintaining a good balance between everything that I do, I can still strive for excellence. I think I should cultivate more initiative and more pro activeness to better help me achieve success. I can contribute to my class by participating more in the activities and mixing with them to negotiate better and avoid misunderstandings.
#4 Bridge Building Activity - Debrief (II) Personal Reflection
I feel that it was quite fun working with my team. There were no quarrels, and everyone was happy working with each other. I would spend more time working on the project instead of fooling around. Fortunately, my team worked quite well together so I did not have any fears or discomforts working with my team.
