It is impossible to live without failing at something, unless you live so cautiously that you might as well not have lived at all – in which case, you fail by default.
There is something good in all seeming failures. You are not to see that now. Time will reveal it. Be patient.
Restlessness is discontent — and discontent is the first necessity of progress. Show me a thoroughly satisfied man — and I will show you a failure.
Our virtues and our failings are inseparable, like force and matter. When they separate, man is no more.
