[1V] First Willpower: Tendency to proactively take responsibility for their own and others actions. A driven person motivated to lead, carry the heavy load and push projects forward. Very good at overcoming odds, working towards achieving their goals and knowing what they want. Does not take the will and desires of others into account. They excel at leadership, yet they are bad at teamwork, believing that the only way to get a job done well is by doing it yourself. Unable to adequately compromise their own wishes or desires, making them appear rather undiplomatic at times.
[1E] First Emotion: Naturally fluctuates between emotional states and spices up everyday life for themselves and others. Done through an active meeting with their world with a real enthusiasm or passion in their own personal endeavors thereby always acting authentic to their own feelings. They will often act unfiltered on their own emotions, not taking into account the positions or emotional effect their behavior has on others. Can have a tendency to overdramatise a situation and not dealing with things in a level-headed way, thereby blowing them out of proportion and escalating conflicts.
[1L] First Logic: A know-it-all. Readily and confidently provides clear and unambiguous answers and opinions. They are steady, reliable sources of information and excel at giving closure to otherwise uncertain ideas and thoughts from a solid and strong framework. Dogmatic and inflexible in their opinions. Consider that their own ideas are right by default and those of others are inferior. Has a very hard time admitting to mistakes and can pull up an arrogant and unapproachable facade. Will often dismiss ideas not fitting their own thoughts instantly without giving them the consideration they require.
[1F] First Physics: Has a strong idea of their material wants/needs and the state of their physical selves. Combined with a natural sense of ownership and knowing just what they need to enjoy life. Hyper aware of how something makes them feel (physically) and actively take steps to pursue the positive states while avoiding the negative. Overly materialistic and superficial in their approach. Focused on their own pleasure and material needs, which can make them rather greedy and egoistic, and disinclined to share anything. Can also appear lazy and spoiled, by being unwilling to change or make any compromises in their lifestyle.
