Hello there

Tell your parents that not following passion of anything into which you're having interest will make you stuck in an endless misery just because anything into which you are not having interest will make you stressful and filled with anxiety as the work will not give you a feel of adventure, which everyone needs. And yes engineers are totally jobless nowadays, only those can survive and excel who've interest into it. And as you said you don't have interest then I'm damn sure you will not be able to earn properly in this era.

I hope it helps you!

Thank you!
