Don't dwell on what went wrong. Instead, focus on what to do next. Spend your energies on moving forward toward finding the answer.
Success is almost totally dependent upon drive and persistence. The extra energy required to make another effort or try another approach is the secret of winning.
You have all the reason in the world to achieve your grandest dreams. Imagination plus innovation equals realization.
Listen to the desires of your children. Encourage them and then give them the autonomy to make their own decision.
Change the changeable, accept the unchangeable, and remove yourself from the unacceptable.
