I have a state of being bored but I’m excited about how to improve myself and need to keep pushing myself. I can’t find a word to fit this state of being bored but with lots to do – ultimately lacking motivation to do (tedious, repetitive) work, when one feels one should be motivated due to the amount of work needed to do.

Neither indifferent ( having no particular interest or sympathy ) nor frustrated ( feeling or expressing distress and annoyance resulting from an inability to change or achieve something ) seem to fit the desired word, although both are relevant.

Why it is no longer that work effectively causes boredom, but rather a factor relating to frustration.
