How far are you willing to go to complete a job? Do you stop at O.K.? How about good enough? If your attitude is to just meet a low threshold, then you can never achieve excellence. It may be menial work that gives you no pleasure. It may be that you would rather be doing something else so you rush through your work and do just enough to get by, just so nobody complains. It may be that you will get no recognition no matter how much effort you pour out. However, I would argue that a slothful approach to one's work, a poor work ethic, and a point of view where one is always seeking to cut corners, are not just poor character traits, they are wholly unbiblical attitudes. There are several relevant reminders in the book of Proverbs.
Proverbs 14:23 - "All hard work brings a profit."
Proverbs 18:9 - "One who is slack in his work is brother to one who destroys."
Therefore as you go about tasks in your workaday lives, keep in mind that giving your full effort is a Godly way to approach your responsibilities. Good work habits lead to success and consistency in our approach and are essential to stave off bad habits. Seek excellence in all that you do.
