After all, what does fame everlasting mean? Mere vanity.
Think nothing profitable to you which compels you to break a promise, to lose your self respect, to hate any person, to curse, to act the hypocrite.
Leave other people's mistakes where they lie.
Do what you will. Even if you tear yourself apart, most people will continue doing the same things.
You have to assemble your life yourself - action by action.
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.
