Don't dwell on the problem, concentrate on the solution. Resolve how you can, not lament why you can't. Forgive and go forward. Grudge blocks positive. Until you clear the past, you are destined to repeat it.
Self talk equals self performance.
That is what you will become. Spend 15 minutes a day focusing on a positive picture. What you do off the job determines what you are likely to do on the job. Strengthen your weaknesses and strengthen your strengths at the same time. Combine positive with negative for better personal development results Failure is an event, not a person.
