William Arthur Ward,
The mistakes to avoid:
- Remorse over yesterday's failures.
- Anxiety over today's problems.
- Worry over tomorrow's uncertainty.
- Waste of the moment's opportunity.
- Procrastination with one's present duty.
- Resentment of another's success.
- Criticism of a neighbor's imperfection.
- Impatience with youth's immaturity.
- Skepticism of our nation's future.
- Unbelief in God's providence.
