I am a new student in an engineering college. What is your advice for me?

Shaykh Ṣāliḥ al-Fawzān:

My advice is that you study the matters of your religion first. When you have studied the matters of your religion, then there is no problem if you study a worldly trade or something you incline towards and are able to be productive in. However, this is after you have studied matters of your religion.
