Ive narrowed it down to these three virtues, but I am finding it hard to pick which one to use to personify in my character.

Plate 1 of classical virtues: Diligence. She is holding a whip and spurs, signifying a drive to steadfastly move forward with one's means.

Diligence is steadfast application, assiduousness and industry; the virtue of hard work. It is one of the seven heavenly virtues. Diligent behaviour is indicative of a work ethic; a belief that work is good in itself.
A zealous and careful nature in one's actions and work; decisive work ethic, steadfastness in belief, fortitude, and the capability of not giving up. Budgeting one's time; monitoring one's own activities to guard against laziness. Upholding one's convictions at all times, especially when no one else is watching (integrity).

Patience (or forbearing) is the state of endurance under difficult circumstances, which can mean persevering in the face of delay or provocation without acting on annoyance/anger in a negative way; or exhibiting forbearance when under strain, especially when faced with longer-term difficulties. Patience is the level of endurance one can take before negativity. It is also used to refer to the character trait of being steadfast. Antonyms include hastiness and impetuousness.
It is Forbearance and endurance through moderation. Resolving conflicts and injustice peacefully, as opposed to resorting to violence. Accepting the grace to forgive to show mercy to sinners. Creating a sense of peaceful stability and community rather than suffering, hostility, and antagonism.

Chastity is sexual behaviour of a man or woman that is acceptable to the moral standards and guidelines of their culture, civilisation or religion. In the Western world, the term has become closely associated (and is often used interchangeably) with sexual abstinence, especially before marriage.

Abstaining from sexual conduct according to one's state in life; the practice of courtly love and romantic friendship. Cleanliness through cultivated good health and hygiene, and maintained by refraining from intoxicants. To be honest with oneself, one's family, one's friends, and to all of humanity. Embracing of moral wholesomeness and achieving purity of thought-through education and betterment. The ability to refrain from being distracted and influenced by hostility, temptation or corruption.
