…you’re having a bad day.
…you don’t feel well.
…your car breaks down.
…your computer is acting up.
…you don’t feel like working.
Your clients hired you to do a job. They only care about the outcome. Do the job you said you would do in the timeframe you said you’d do it.
Don’t complain. Don’t make excuses. You signed up for this.
Shake off everything else and hunker down and get it done.
