The decision was a no-brainer but even so, the temptation for me to continue with the landing and to try and resolve it in the flare was ENORMOUS. Can't quite state that enough.
My PPL instructor drove this point home on almost every flight we did together:
"the decision to G/A is way harder than to continue the landing"
He would try to distract me in the flare or he would land the airplane halfway down the runway and then ask me "go or stay". Got my attention and although I had to G/A only maybe 5 times in the 26 years since my PPL I always thought that to be one of the most fundamental lessons I ever learned.
