A man must stand erect, not be kept erect by others.
Do not think that what is hard for you to master is humanly impossible; but if a thing is humanly possible, consider it to be within your reach.
Remember that to change your mind and follow him who sets you right is to be none the less free than you were before.
Submit to the fate of your own free will.
Enter others' minds and let them enter yours.
If you do everything as if it were the last thing you were doing in your life, and stop being aimless, stop letting your emotions override what your mind tells you, stop being hypocritical, self-centered, irritable.
