Things do not happen. Things are made to happen.
Well done is better than well said.
It's always too early to quit.
Quality is not an act, it is a habit.
Without hard work, nothing grows but weeds.
If you're going through hell, keep going.
If you think you can do it, you can.
After a storm comes a calm.
Either you run the day or the day runs you.
Always desire to learn something useful.
A love of nature is a consolation against failure.
