Which career is more profitable, digital marketing, website development or mobile app development?

See, according to me each field is dependent of another, you can create a application but what’s the point if you can not market it? and what will you do with only marketing if there is no product to sell.

Apart from that I believe that world is going to be fully digital by 2020 so all above mentioned career can be “profitable”, if you are really into the thing.

Almost all thing you can do now with mobile app now days, there are healthcare apps, entertainment apps, service providing app like UrbanClap - Service Experts | Hire Wedding, Home & Beauty Professionals and many more, from taxi booking to ordering food & booking doctors appointment we use just app.

I think by now you must have found your answer. My intention was never to confuse you, but just to clarify the definition of profit in your mind.
