Calling yourself hardworking without logging hours is a title you gave yourself with no interview.

Self-description is free, which is why it drifts from the record so easily. Almost everyone believes they work hard, and the belief is sincere, because effort feels much larger from inside than it measures from outside. Without a count you are grading yourself on intensity of feeling rather than on hours, and the two are not closely related.

Count one week without trying to improve it. Just the real time spent on the thing you say you care about, in honest blocks. Whatever the number is, you will know something true and can work from there.
