If you don't like what you are doing, you better leave. You wont be good and happy doing something you are not keen of.

I'm in the programming line and I find it challenging. You need to find something you are passionate about and do it. Sometimes I work 24 hours continously to get the job done. But I rather be tired than bored. So my advise if you are feeling bored, is to find another job/task that will make you so tired that you won't have time to feel bored
