How can one motivate oneself to study and achieve one's goals when one hates one's university major and feels indifferent towards studying?

The strongest motivator for studying is the pursuit of a specific goal. By defining the goal and desiring it, the intended outcome will be achieved, Allah permitting. Studying without a goal becomes a burden and an unnecessary, useless cost. Some aids to studying have been mentioned in fatwas numbered: 51292, 38910, 42671, 37175, 43852, 40845.
