When i was a student I used to think that doing a job and earning money is much more easier than studying and passing an exam!! But guess I was totally WRONG! Yes, earning is the most difficult thing in your life and earning with respect is much more difficult than that Your body will be cover from pain, you will feel headache but you have to work like a machine and earn for yourself and your family :) So enjoy your time along with studies because professional life is a real hectic
