I've done a lot of things in my life that would make people nervous but for some reason never made me nervous. Jumped off cliffs, slammed on reefs, ate it from ten feet above the lip on a BMX bike, hooking up my back truck on the coping learning frontside ollies over the canyon, gotten married, had kids etc, etc. The list is almost endless.
As crazy as it might sound, the most nervous I've ever been in my life has been today with the launch of the project I've been working on for the last waaaay to long, 360 Quick Connect.
It's going to change how you use your GoPro. With 360 Quick Connect you can change mounts in seconds, put your GoPro on any angle, line up shots precisely and so much more. It's amazing. Backwards and forwards compatible with every GoPro mount you own it will make you a better photographer and filmmaker because now you have complete compositional freedom to set up the shots the way you like them.
P.S. Check out how fast 360 Quick Connect is compared to GoPro's system.
