Sophie Germain

The only true wisdom is in knowing you know nothing.

The unexamined life is not worth living.

I cannot teach anybody anything. I can only make them think.

There is only one good, knowledge, and one evil, ignorance.

The beginning of wisdom is the definition of terms.

The greatest wealth is to live content with little.

The only thing I know is that I know nothing.

The secret of change is to focus all of your energy, not on fighting the old, but on building the new.

The journey of a thousand miles begins with a single step.

The best way to predict the future is to create it.

It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is most adaptable to change.

The mind is everything. What you think you become.

Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment.

Believe you can and you're halfway there.

The best revenge is massive success.

The only limit to our realization of tomorrow will be our doubts of today.

It is during our darkest moments that we must focus to see the light.

The future belongs to those who believe in the beauty of their dreams.

The only person you are destined to become is the person you decide to be.

Strive not to be a success, but rather to be of value.
