The opportunity to use one’s creativity to make a living is a rare thing in the history of the world. For that, give thanks.
You cannot make someone listen, care or invest emotionally in your brand. All you can do is be honest, be interesting and get lucky.
You sell an idea by promoting the value it will produce, not the production values it will require.
Never trust an agency that treats creative work as a bonus to sell you their services instead of as a bedrock of selling your brand.
