If you wish to live a life free from sorrow, think of what is going to happen as if it had already happened.
Happiness and personal fulfillment are the natural consequences of doing the right thing.
Getting distracted by trifles is the easiest thing in the worldโฆ Focus on your main duty
No living being is held by anything so strongly as its own needs.
Don't regard what anyone says of you, for this, after all, is no concern of yours.
If you hear that someone is speaking ill of you, instead of trying to defend yourself you should say: 'He obviously does not know me very well, since there are so many other faults he could have mentioned.'
