No you are not spreading yourself too thin. Each new language or framework you learn will teach you something you’ll use for the rest of your time programming.

No you are not spreading yourself too thin. Each new language or framework you learn will teach you something you’ll use for the rest of your time programming. You may not remember everything you learn exactly, but it will help you carry conversations or know where to start should you be tasked to need those skills in the future. Also Google is your friend, you’re never going to know some language or framework so completely that you can verbatim spit out it’s docs and signatures without some reference. The rest of what you said sounds pretty on par with the rest of the self taught programmers I’ve met (me being one of them).
