It's always too early to quit.

Without hard work, nothing grows but weeds.

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

If you're going through hell, keep going.

Be gentle to all and stern with yourself.

Problems are not stop signs, they are guidelines.

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

Be thine own palace, or the world's thy jail.

The dog that trots about finds a bone.
