Why did I grow to like studying?
It's about perspectives. Relating findings in one discipline to questions in another context, such as my work life. It feels more rewarding to theoretically explore current issues at work, rather than merely memorizing (seemingly) abstract stuff for an upcoming exam.
And it's about giving back. With the benefit of experience, I find myself in situations where I can contribute. Students and lecturers expect me to offer my input.
How could I not feel motivated?
