I'm the same way, yes, since I was 15. I'm nearly 45. My view is: technologies change. It's hard to be a master in any single technology lasting for longer than a few years. Better to be a master in a specific industry than a specific technology. I was thrust into healthcare IT early in my career. Not my favorite, but I'm no longer lost in this very-hard-to-navigate industry. I can not only talk tech, but I can talk show with non-tech people, including physicians and medical directors, CEOs of large insurance plans, etc., without looking like a fool. The key is to find the industry you're passionate about, then apply your technical skills there. Just my opinion.

Iván I also know how you feel. I think the best suggestion I can give is related to your interests and popularity. The town I live in, it seems that 80% of the jobs are .NET. I used to be a ColdFusion developer, but the company I worked at started to downsize. So I learned C#. I actually love the language now. But it was a big step making the professional transition.

I am now an iOS, Android and Node.js developer. I got real interested in mobile development when the iPhone came out in 2007. So I taught myself Objective-C. I am now learning Swift. It became enough of a passion for me to where I sought out a job doing iOS development fulltime, even though it is not a common discipline in the part of Florida where I work.

I think you will find in the course of your career that you will have to learn new languages and frameworks.

Be flexible and learn things.

I know how you feel. I worked as a consultant for a while and people would be like: hey, don't you want to do front end for my project? And I would be like: sure, what do you need? And it seemed like every new job was a different framework or set of tools... And so I stumbled along from project to project feeling like (perhaps read the article on imposter syndrome ) I didn't know anything; that I was a newbie all the time... Even though I was doing cutting edge stuff. And worst of all: I completely undercharged and underestimated my skills and abilities. But truth is, I could see a strain of development. I could see myself improving; and I started to see which areas I enjoyed and wanted to work in by my experiences. I identified a common thread throughout and understood: this is what I would like to specialise in. This is what I want to be good at. And I started to focus on those things. I am not recommending that this is a good way to do things, but I always find work as a javascript dev and I am really enjoying my current assignment 😊

Depends on what you're aiming in your future.

Being a jack of all traits works splendid for me and I enjoy to understand multiple language and systems.

I would recommend for you to try to get in a company where you like what they're doing and inside you can still decide what to do or just jump around who cares if you good at it.

Don't let the public opinion reduce your curiosity to know a lot of things.

For me learning concepts is more important than learning to use a specific language.
