For most things in life we need to keep practicing to get better. We need to show PERSEVERANCE to overcome challenges. We make mistakes and it can be frustrating, but we need to practice, practice, practice. When possible, we need to find a way to make it fun and enjoy it. Learning a language is no different. If this young kid can show perseverance, so can you!
There are some things in life that are not that much fun to practice for some people, but we still need to learn how to do. For example, some people don't like math, but we need to learn math to manage basic things like groceries or paying rent!
Learning a language can have things you like and some that require a little more grit, but the advantages of being multilingual at any age are very powerful so don't give up and keep going!
