How do you want to be judged, by how busy you appear to be or by how much you get done?
One way of judging how hard you are working is by how much of your time is occupied. The other way of judging is by looking at how much you accomplished in a given week / month / year / career.
So do you say "I worked 70 hours last week!" or do you say "Last week I finished an article!" Note the difference.
Now maybe you worked 70 hours and finished something too; that's great, but only the accomplishment really counts, in a way. The rest is what you had to do to get it done. You wouldn't judge how much you wrote by how many bottles of fountain pen ink you went through either, or your success in sales by how much gas or shoe-leather you consumed.
