Reputations are earned slowly and are lost quickly. (Lolly Daskal, leadership and development motivator)
The reputation of good character and a solid work ethic are earned only through consistency and hard work. But it takes only a moment of carelessness to destroy that hard-earned reputation. The more you achieve, the more tempting it will be to take shortcuts or forget how far you’ve come. Diligence and discipline are the keys to maintaining character.
Do not neglect your gift … Be diligent in these matters; give yourself wholly to them, so that everyone may see your progress (1 Timothy 4:14-16 )
