In this industry, change is the only constant and your ability to learn, grow, and adapt is going to be more important than any singular technology you can learn.
I can promise you’re not as stupid as you may feel you are. You’ve made it a year, and that means something.
I’ve been pushing myself hard to get some certifications to really deepen my skill set. You may find that’s valuable to you, or you may not. I’ve found that it’s improved my ability to take a step back and understand the systems I’m building from an architectural perspective. It’s been helpful for me.
I’ve helped coach interns and new hires at my company before. I actually like when they ask me questions even if it’s something I’ve answered before, because it shows me that they want to learn. And even better is when they ask “why do it that way?”, because it forces me to check my own understanding of the problem set. It also means that I can really dig into the explanation and hopefully they walk away with at least one more tool in their toolbox.
