alt Hacker NewsYou're getting dunked on a little bit in the replies, but your point of view is important for people to read. Not everyone is capable of learning every skill, and practice is necessary but insufficient. I've been on and off trying to learn a foreign language for decades, and it just doesn't click, no matter what I try (formal lessons, immersion, book study, apps). I used to have the "Just practice, bro" attitude, but I've done a 180 over the years and I have a lot of empathy and understanding now when my own kid complains "I just can't learn this."
It's also about how you practice. It's true that not everyone can get to any level at any skill. But it's also true we underestimate our abilities and potential almost universally. That said where you invest your limited time and what you enjoy and want to work on is totally up to you. But often "I can't do it" is just an excuse or a mindset or not having found the workaround or the right approach (where a teacher can sometimes help).
