How can you constantly improve your media skills? A lot of things in life if you focus on it, analyze what you're doing, you can make things better. Imagine if you're back in fifth grade, trying to learn how to write good essays. Teacher marks up your paper and you never look at you don't know where you forgot a comma forgot a capitalization didn't use quotation marks the right way. how good of a writer would you have become? learning how to speak to the media is no different.
If you want to get better if you want to improve. You've got to look at what you're doing. That means every media interview you do you need to watch it on video or listen to it if it's radio or read it if it's in a newspaper or in an online environment and you need to hold yourself accountable. Did you get the exact message across that you wanted? Did you get the quotes that you want to? If it is on video, do you look natural, relaxed, comfortable, confident Are you fidgeting with fingers and rings and eyes darting around, really hold yourself accountable.
Look at every single interview, make notes of not just what you didn't like what was bad. More important is to make notes on what worked. What did you like so you can do more of it that's actually more important than trying to fixate on the negative. If you analyze every MIDI interview you do, and you try to get just one half of 1% better for the next one. Over time, you'll get better and better and better. Eventually, you will be great
