The Nike logo, Hershey's Chocolate, the opening score to Star Wars; as you read each of those you probably recalled each within seconds. There are few things that multiple generations and cultures can instantly recognize and relate to, but those things are worthy of the adjective: iconic.
Perhaps it's the level of quality, immense marketing behind a brand, or the creativity was truly impressive, but something made those items rise above the rest. As creators, we aspire to make something that stands the test of time, but rarely does that motivation alone cause a breakthrough.
Perseverance, obsessive search for quality, determination, innovativation; these are the things we should seek. Aim to make something great that will improve or help the lives of those around you, do it well enough, and perhaps it will last for generations.
