A man must be big enough to admit his mistakes, smart enough to profit from them, and strong enough to correct them.
A man who has committed a mistake and doesn't correct it is committing another mistake.
A problem is a chance for you to do your best.
Orison Swett Marden
All who have accomplished great things have had a great aim, have fixed their gaze on a goal which was high, one which sometimes seemed impossible.
Norman Vincent Peale
Believe it is possible to solve your problem. Tremendous things happen to the believer. So believe the answer will come. It will.
Do not think of your faults; still less of others' faults. Look for what is good and strong and try to imitate it. Your faults will drop off like dead leaves when their time comes.
Don't dwell on what went wrong. Instead, focus on what to do next. Spend your energies on moving forward toward finding the answer.
Don't find fault. Find a remedy.
Focus on remedies, not faults.
