Using the 'Personal A'
When you influence a specific person or people, you must use the word 'a' before them. For example: 'Él influencia a su hermano' (He influences his brother).
Desires and Influence
If you are trying to influence someone to do something, the second verb needs a special form (the subjunctive). For example: 'Quiero que el libro te influencie' (I want the book to influence you).
Don't use 'en' with 'influenciar'
