Do something you have never done before.
Start a podcast. Get your voice heard and talk about what you love to do. Whether it be informational or just sharing your journey, get out the mic and speak. Have guests, talk about your photography, talk about your challenges as a creator. Whatever it is, let your voice be heard.
Blog. I know a lot of people are not fans of writing but this is a great tool and a blog page should be on your website. If you already journal, publish it to the world. Write about your photo shoots or the process of how you do what you do.
There are so many other ways to get outside focusing on your main creative skill and keep the inspiration going and to be able to fill the gaps when your main thing feel stale.
Don’t just focus on the main thing.
