Hi Monica
I feel that what you've outlined above is good advice for entrepreneurs who want/need to establish a perception of their brand in their own minds.
Once they have figured it out for themselves they will benefit from working with professional graphic designers who can visually articulate the message for consumer consumption.
Ultimately, the brand will be defined by consumer perception (which may be different than your own original perception), and there are innumerable mitigating factors. You can't determine how people will perceive things, but you can leverage design to communicate the message you wish to send, and to make emotional connections with consumers.
Branding isn't a science. It's persuasion. And persuasion is an art.
All the best!
