Art is made up of two parts; creativity and craft. Craft is the artistic skill to make the art, while creativity is the imagination behind it.
Craft is how you do stuff. It is the byproduct of working hour after hour, week after week, year after year. It is something you acquire by learning a skill. If you want to develop your craft, put in your time.
Creativity is the way in which you use craft. You can be creative without being a great craftsperson. If you are creative and busy, or creative and affluent, you can hire someone with craft to execute your creative ideas.
Think you aren’t creative? You probably just lack the craft.
