My Olympic coach told me after a particularly challenging workout where I could not hit my splits before going to the Rio Olympics that that was okay it was the rule of thirds—and he was an Olympian so I was, you know I always soaked in everything he said.
I was like what's the rule of thirds?, and he said when you're chasing a dream or doing anything hard you're meant to feel good a third of the time okay a third of the time and crappy a third of the time and if the ratio is roughly in that range then you're doing fine.
So today was the crappy day along your dream chasing right and if the ratios off like you feel too good all the time or too bad then you you got to look at if you're fatiguing or or not trying hard enough for pushing yourselves.
