Well bro, I don't think there is any job you don't have to learn new thing, because if you stop learning you will be kicked out of the boat. So I think you should continue doing your job.
Believe me, there are a lot of people now wish they should have learnt IT to be able to get a job. App developer is hot subject in job market now tho.
I suggest you should learn to invest something, so when you have passive income, you can leave your job and retire early.
