To know oneself, one should assert oneself.

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

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

Without hard work, nothing grows but weeds.

If you think you can do it, you can.

It's always too early to quit.

You never know what motivates you.

Quality is not an act, it is a habit.

Problems are not stop signs, they are guidelines.
