Be gentle to all and stern with yourself.

Do not weep do not wax indignant. Understand.

Problems are not stop signs, they are guidelines.

The wise does at once what the fool does at last.

Without hard work, nothing grows but weeds.

It's always too early to quit.

Go for it now. The future is promised to no one.

Always desire to learn something useful.

Know or listen to those who know.
