 Well, mathematics is always under everything, so just be comfortable with that, don't be afraid of it. Often with mathematics, things appear difficult when you first see them, and it's like learning a new language, it just sounds like nonsense, and then you start with the simple things and build up. So math is always useful, so always try to find a way in to the learning new mathematics. Things like physics, chemistry, biology, those basic disciplines will always be important.
