I'm looking to grow as a Software Engineer, and I would love to hear ideas about things one can do outside the office to progress your career.
I was going to include a list of things that I've done/I'm doing, but I rather get fresh ideas and not bias the conversation.
If you're more senior, the biggest impacts will come from networking. Figure out where you want your career/life to go, then work towards that. Want to be CTO? Want to work at XYZ tech co? Want to start a business? Doesn't matter, make some friends and start networking.
I'm a big advocate for leveraging the energy of your youth, but make sure you're spending it wisely. There's more to life than working.
