What factors influence handwritting?

Handwriting is influenced by various factors, including individual physiology, such as fine motor skills and hand-eye coordination, as well as environmental aspects like the writing surface and tools used (e.g., pen or pencil type). Psychological factors, including personality traits and emotional state, can also play a role, as handwriting can reflect one's mood or level of confidence. Additionally, educational background and practice can shape handwriting styles and legibility over time.
