Perseverance is the hard work you do after you get tired of doing the hard work you already did.
Most of things you do in life are habit-forming. Perseverance is no different. The harder you work at the things that matter the most to you, the more difficult it becomes to quit. Ask God for courage to work hard so that you can more completely fulfill His plans for you.
The soul of the sluggard craves and gets nothing, while the soul of the diligent is richly supplied.
