Getting started with anything is easy. Anyone can become a writer, singer, designer, illustrator, entrepreneur, you name it. But only a few keep going.
For example, a lot of people want to start a business. But it seems like the emphasis is on starting. Most businesses don’t exist after 5 years.
Same thing with creative professions. Aspiring writers start off strong and write for several days, weeks or months, and then move on to the next thing that catches their attention.
