Problems are not stop signs, they are guidelines.

It's always too early to quit.

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

Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

Always desire to learn something useful.

Do not weep do not wax indignant. Understand.

What you do today can improve all your tomorrows.

You never know what motivates you.
