Training life pie chart

My coach sent me this pie chart so I have some reference and boundaries as far as training for Ironman goes...  

Perhaps I should have looked at this prior to starting this journey?!  

She added:  "If work or personal or family gets bigger, training has to get smaller. But your body is a pie chart…you are limited in how much life load you can take."

I have a feeling I will be referring to this often!!!
