You never know what motivates you.

I can, therefore I am.

What you do today can improve all your tomorrows.

By failing to prepare, you are preparing to fail.

To know oneself, one should assert oneself.

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.
