Maybe so, but give yourself top points ONLY if you have convincing evidence that your readers need to hear what you have to say to them. Lots of would-be publishers forget to make sure there is a deep and abiding need in the world for the information they want to provide. Success takes several years to achieve for most newsletters or magazines. For example, if you want to write about your divorce, write a book, don't launch a newsletter. Hopefully, you'll soon recover from your divorce and move on to a different topic.
Periodical publishing is a very risky business with an extraordinary failure rate.
There are lots of ways to control the risks if you are willing to consider them. For example, getting other people involved, either as investors or as contributors can vastly improve your odds of success. The more you know about your subject, the greater your odds of success will be. Adding Up Your Score Rate yourself on a scale of 1 to 5 for each attribute where 5 is extremely strong and 1 is extremely weak. If you score below 10 points, better look for a job on someone else's publication instead of starting your own.
