Sometimes I wonder how often these "productivity tips" mask a deeper feeling of indifference or rejection of the task entirely. People spend hours finding the right tools for a task thinking it will make them want to do it instead of examining the task itself and their feelings around it.
To a certain extent I agree. If you were really passionate about something like this you would make it happen regardless of your circumstances. Think about kids who grow up in impoverished island nations who make it to the MLB through sheer perseverance.
The difference is unless you're already wealthy or talented, you _need_ to write effectively to compete in the modern 'white collar' workforce.
Writing something that people want to read is very hard. People don't read for the sake of reading, they read to learn something or feel something. It can take years of consistent practice to evoke anger, sadness, or laughter through writing. Think about how many books, workshops, and college courses there are on writing itself. It is sort of like programming, it is a skill that anyone can learn given enough time and it has very little barrier to entry. This makes it extremely competitive, so a lot of people need to exploit whatever edge they can get.
