        <h5>Why we want to make the world beautiful</h5>
        <p class="">Het ergert en irriteert mij persoonlijk wanneer mensen geen aandacht hebben gestoken in de offline/online uitingen. Dit kan een website zijn die niet functioneert op een mobiele telefoon, afbeeldingen welke niet geschikt zijn voor een retina scherm of uitingen welke geen verband houden met waar het bedrijf voor staat. Daarnaast wordt ik juist vrolijk wanneer bedrijven/mensen er juist heel veel aandacht en energie in hebben gestoken. Uit deze haat/liefde verhouding is mijn motivatie gegroeid om Creative Unity op te bouwen.</p>
