“As a new entrepreneur should you have one ideal client to focus on or is good to spread the wings a little and try out different clients?”
The answer is it depends. Ideally you should focus your time and energy on your perfect ideal client. That is how you will reach the most people, you will make the most sales, and it will make you happier.
That being said if you don’t know who your perfect client is, you might have to go and explore different types of clients to see what you work best with.
