Tired is not the word you use when you really mean weary when you really mean tapped out when you really mean that you just don't have the words or the patience or the foresight or the wherewithal. Tired is not the word you use.
When they ask how it's going you say that it is, going which is true because in fact there is no stop, no pause, no break in the action, it's going as you said, there are no lies, it's going and hardly matters how just that it's going and we see that's going and we ask how it's going as a courtesy not an investigation. It keeps going and I keep saying so.
Tired is not a word you use when you really mean overextended when you really mean depleted when you really mean imbalanced when you really mean that you are no longer sure what counts as any of those things only that you expect to keep going until you can't because if you can't find the word, how can you possibly define the reality?
When they ask you if this is the best you've got and if this is what it's going to be and if you're planning to send it out like that and if you're sure this is how you want it to look and you don't say, you just stare and stare and stare. Tired is not the word you use. Tired is not the word.
