It’s hard and it’s boring

I have decided to change a career and try to get into IT industry because it is always hiring and pays well. Right now I am preparing for my second interview in this Tech giant. I am sure that I want the job but I need to learn a lot of technical things in order to get it. I need help with a reoccuring thought about it which doesn’t let me to focus on preparation. I think “It’s hard and it’s boring”. Why would I even want a career which makes me think that? How would I be selling a product which I consider hard to understand and boring. I want to change my thought. I want to be fascinated with the product and concepts. But right now it doesn’t seem believable. So I am trying to persuade myself that I can love and be good at something even if I consider some parts of it hard and boring. Am I on the right track?
