...is to understand that your job or career or goal requires you to keep showing up regardless of how you feel. Putting in your best effort each and every day will build the grit required to to great work. There must have been days when Michelangelo wasn’t jazzed about chipping away marble for hours at a time. He did it though and now we have David.
If you find yourself making the type of excuses that prevent you from showing up, then you may need to rethink your job or career or goal.
