Yup. I learned early on that if anything breaks my concentration during gear setup (ex. Chatting bystander)...stop where I am, go back to the beginning, and repeat the process again.
Yesterday my parents came to watch their grandson get in the quarry and dive with me (he's 14), and they were asking questions. It was hot as hell in a ds and doubles on making my way to shore and in my head I'm like "for the love of god please stop talking". Of course I love my parents but damn...lol.
....but the young ladies walking around in bathing suits have been known to get me off track!
This is me probably until the day I die Thankfully my wife is ok with it most of the time...
