What are your Short/Long Term Goals as a Software Developer? 💻

I'm currently in my nth month and fairly newly-hired software developer and for our first 1-on-1s I was asked what are my short and long term goals.

So for short-term goals, I quickly thought of technical skills which I don't know a thing or just a gist of it that'll be supplemental for my role while a general idea of leadership/management skills for long-term goals.

But that's just me, I want to know what plans/ideas you guys are in preparation for. 📒
