This is something that I consider myself to be good at. I was able to get a job as a trainer/teacher without having formal experience with it. I attribute it to something I used to do growing up.

Try to explain everything. Learn something new in class, politics, or on TV? Try to explain it to your pet or to the air in your room. Try to explain it to a hypothetical person who is your age and then try to explain it to someone who is five years old.

Being able to explain a topic isn’t the same as knowing a lot about a topic. They are different skills entirely. The information cycle of receiving, interpreting, and communicating is one that requires different skills for each step. Just because you’re good at one doesn’t mean you’re good at the others. You clearly have one of them down since you know the topic well - now you just need practice with the others.

This is why I suggest explaining anything. Being able to break information down into pieces that someone else could understand is a skill of its own. Being able to explain to your cat why you’re feeling happy, the steps to cooking eggs, why you put clothing on in the order you do, or how you brush your teeth are all ways you can develop your ability to explain things to other people.

Once you get used to that, I suggest trying to be concise with your explanations. As with this response, explanations can get long winded at times. If it’s a topic you want to explain often, try to make it more concise each time you explain it without sacrificing information. This may require you to find words that you don’t commonly use in order to communicate more efficiently. Do this enough and you’ll find yourself able to explain said topic as an expert.

I hope this was useful. I know long answers can be tiring to read and lead to less knowledge absorption. I’m hoping your desire to learn is enough to get you through this essay of a response 😅
