Problems are not stop signs, they are guidelines.

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

It's always too early to quit.

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

Be gentle to all and stern with yourself.

By failing to prepare, you are preparing to fail.

Always desire to learn something useful.

Begin to be now what you will be hereafter.

Quality is not an act, it is a habit.
