Sometimes, you need to be alone. Not to be lonely, but to enjoy your free time being yourself.
Reflect upon your present blessings, of which every man has plenty; not on your past misfortunes, of which all men have some.
The greatest glory in living lies not in never falling, but in rising every time we fall.
The self is not something ready-made, but something in continuous formation through choice of action.
Without reflection, we go blindly on our way, creating more unintended consequences, and failing to achieve anything useful.
