Keep learning, especially as you get older. I have noticed that a lot of people stop learning (new skills, general knowledge, etc.). Learning should not stop with school, it’s a lifelong endeavor.
I’ve thought about why people stop learning. I believe people are afraid to fail, and learning and doing new things by definition are hard and will likely result in failure. As you get older you forget that even when you were little you struggled and failed A LOT. But the reason you ultimately succeeded is you didn’t give up. Learn to enjoy the failure as an opportunity to debug what went wrong and get better. Learn to look forward to the struggle. Once you master something, it’s a lot less fun. You’ll be dangerous if you can genuinely embrace this mindset.
