Art comes out of making. It’s a practice.
Not everything you make will be great art. Especially at the beginning, most of what you make will be unclear, imperfect, vague, or ineffectual.
But the only way to get good at the craft of making art is by practicing it.
Whatever you want to make, make it. Make more of it. Make 100 podcasts, 100 compositions, 100 songs, 100 paintings. Get feedback, and start the next one.
Do that 100 times, and then see where your craft is. My guess is, you’ll be in a very different place.
Practice making, and worry about the quality later.
