I believe that advertising exists at the polar opposite of immortality. Advertising work that might take months - even years to plan, design, produce and then deploy may only see the light of day once – and then it's history. That said, I still have copies of ads that inspire me which are now 20 to 30 years old. I look at them once in a while, and can see how the media and production technology of their time limited how the type, the illustration and the photography were used. And how some turns of phrase have fallen out of favour, have changed or now mean something very different. Like “stupid”. But I look beyond all that and admire the brilliance of the core messages which still moves me. 

The other day I tripped over an article that referenced Leonardo da Vinci’s diary. It is believed that he started recording his thoughts in notebooks during the 1480s while he was a military and naval engineer for the Duke of Milan. He is widely considered to be the most diversely talented person ever to have lived. Leonardo was an Italian polymath of the Renaissance whose areas of interest included invention, drawing, painting, sculpting, architecture, science, music, mathematics, engineering, literature, anatomy, geology, astronomy, botany, writing, history, and cartography.

Today, over 500 years later, we know all this (to be fact rather than "fake-news") because Leonardo da Vinci kept diaries that preserved his thoughts, insights and his thought processes for “all eternity”.    

Think of it for a minute – or two. We can enjoy his 1st hand accounts and perspectives today because he wrote his thoughts down on paper with good ink.

Nobody really knows what will happen to us after we die, but if immortality is important to you . . . publish your work offline. In books or diaries where your ideas will be preserved and can be shared with the world long after you’re gone.
