I built this sentence:
"I was going to go for a run after waking up from the nap, but I didn't feel willing."
and my English teacher said I should use "...didn't feel motivated" or "...didn't feel up to"
he said the word willing is awkward there. I looked up willing in dictionary and it says something like: "ready, eager, or prepared to do something" so what is wrong with "didn't feel willing"?
