Identify and correct the problems with your product
Get the opinion of someone who is experienced in your field.
If you’re a writer, for example, this person could be your editor. Ensure this is someone you trust and value.
Make a list of the problems this person faced when using your product.
You may not agree with every item on your list, but that’s normal. People are different and you can’t expect everyone to have the same response to your work.
Adjust your product to solve these problems.
Tweak your product according to the list you have created. Think carefully about the problems you don’t agree with - can you imagine how others might face a similar problem?
