I own an entire closet full of tools, from basic hammers and screwdrivers, to drills and circular saws. In theory I should be able to create just about any wooden object my family or I would ever need. Why, then, do I buy all my furniture from manufacturers who make these things professionally? Because I am not a carpenter. If someone came to my home and saw a table that I had built, it would be blindingly obvious. Said table would be structurally unsound and horribly finished. I don’t know enough about making a table, nor about what it takes to make it well. It would be an amateur job. You wouldn’t want it in your home, and neither would I.
A person can purchase the same applications designers used to create professional designs, but that does not make them a designer. Designers aren’t people who merely know the programs available for design. They are not trained monkeys who exist solely to push the correct buttons. Designers are professional aesthetes for hire… people who understand not only the “hows” of design, but the “what works” and “whys”. They have an innate ability to create – to merge word, space, and image in a way that compels.
If I tried to make a table, it would be have four legs and a top… and it MIGHT stand on its own. It wouldn’t be something people would admire, or to trust to do its job properly.
My dinner deserves more that that… and so does your business.
