It can feel daunting in this developer / designer landscape to keep yourself up-to-date with the latest and greatest technologies available. Which new framework should I invest the most time into? Will it even be maintained a couple years down the road? Is it just a fad?
What about programming languages? Should I learn as many as possible or should I become an expert in one specialized area? Should designers code? The list of possible new things you could be learning continues to grow. This is sarcasm. Please don't take this seriously...
Want my advice? Pick something and dive head first into it. Don't worry if it's not the most popular programming language or if it's a new design system that isn't gaining much traction. Do you find it interesting? Awesome - that's what matters most. How can you teach yourself something new when you have zero interest in it?
So what am I currently doing to keep my mind fresh and thinking outside of my comfort zone?
Programming your brain to learn something new can be frustrating and pull you out of your comfort zone. Don't let this become stressful - instead use it as inspiration to push yourself through the struggle.
There is no real reason to avoid learning something new outside your current circle of knowledge - only crappy excuses.
Get on it.
