I will try to lay emphasis on the most important ones, as there may be hundreds if not thousands of other traits that could be jotted down in this respect.
1. Intellectual aspects: We perceive in unique way. If an event is asked to be described, no two accounts will have same wordings and way of description, yet the observation will be an accepted commonality.
2. Feelings based on observations: All of us have different ways to feel.
3. Feelings based on thoughts: Likewise, we do that in different ways.
4. Reactions: We respond and react in different ways, some are oddly.
5. Plans: We have different ways and approaches to planning.
6. Prioritize: Our priorities and giving weight to them may vary.
7. Reliance: Our weights on different factors may not be same.
8. Risk perception: We may not have same risk assessment.
9. Emotions: We all exude emotions uniquely, although with some generality.
10. Decisions: Our taking decisions, after wading through uncertainties, a very complex phenomenon, is based on very different patterns of studied through neuroscience.
There can be lot more that could be enlisted; I stop here.
