Don't be afraid of failure. This is the way to succeed.
There is no greatness where there is not simplicity, goodness, and truth.
It had long since come to my attention that people of accomplishment rarely sat back and let things happen to them. They went out and happened to things.
Leonardo da Vinci
Make your work to be in keeping with your purpose
Study without desire spoils the memory, and it retains nothing that it takes in.
If there's a single lesson that life teaches us, it's that wishing doesn't make it so.
