This is my experience from MinneDemo 22.
My team, presented a demo for our new app, TwistJam. Everything was great, except there was no music or any sound during our speech because of an issue with an audio cable. And we didn’t have a backup plan. Considering TwistJam is a music app, it would have been much better if we had audio during our presentation. There were two audio cables. We checked one and it was working, so we assumed the other one was working fine as well, so we didn’t check it. My point is always double check anything that could make your plan fail. Always prepare a backup plan to deal with any situation that might happen. Sometimes, your opportunity is once-in-a-lifetime. Don’t let those details derail your hard work. “You only get one shot, do not miss your chance to blow!”
