Good Morning from Costa Rica! I came to Contra because, after years of creating ads, running businesses, and overcoming hard times over and over again...I learned. I got better. Instead of lamenting temporary difficulties...I became grateful for the "no", as it always led to the "yes" as long as I had faith and kept going. By far, the talent I cultivated that I loved the most is advertising. That feeling when you create copy, make images and videos, build websites...grow businesses...and the audience reacts with applause by engaging, clicking, and converting? It's totally worth the hours of tweaking, refining...obsessing over every detaill until it's just right! I know many of you feel the same way, so I just wanted to share some grace this morning! I hope today is your best day :-)
