What does a good designer need?

"You're creative, you'll finish it fast" - how many times have you heard this sentence?

In the world of design, many people think that creativity is all we need to be successful. However, there is a lot of research, training, a lot of work, mistakes, rules, requirements, thinking behind it. Creativity is just one item in a series that differs us from others. It is because of this thinking that today we have many young designers with so much potential who do not know how to use it, because they do not work on themselves and think that talent is the only thing they need.

What is your work process? What do we need to be good designer?
