Installing a large 5-meter long banner in the very center of a city in winter is never easy. Even though I thought we had it in terms of the engineering thought, it always feels different once you're actually in place and ready to fire. Our initial plan for where and how we should hang the banner didn't seem viable at all that morning. However, I was mentally way past the 'no turning back' point, and thanks to our background in engineering, we managed to re-adjust the plan using all the utility we had on us.
Always trust the process. And believe in your success.
