Meditate upon what you ought to be in body and soul when death overtakes you; meditate on the brevity of life, and the measureless gulf of eternity behind it and before, and upon the frailty of everything material.

Some suggestions for you :

If it is not right, do not do it: if it is not true, do not say it.

For a man cannot lose either the past or the future: for what a man has not, how can any one take this from him?

Confine yourself to the present.

And he cares nothing for their praise—men who can't even meet their own standards.

The pomps and glories which he despised were all his; what to most men is an ambition or a dream, to him was a round of weary tasks which nothing but the stern sense of duty could carry him through. And he did his work well.

If you remove your judgement of anything that seems painful, you yourself stand quite immune to pain. 'What self?' Reason. 'But I am not just reason.' Granted. So let reason cause itself no pain, and if some other part of you is in trouble, it can form its own judgement for itself.

He claimed that a man's life should be valued according to the value of the things to which he gave his attention.

Neither worse then or better is a thing made by being praised.

You always own the option of having no opinion. There is never any need to get worked up or to trouble your soul about things you can't control. These things are not asking to be judged by you. Leave them alone.

Let no act be done without a purpose, nor otherwise than according to the perfect principles of art.

For the present is the only thing of which a man can be deprived, if it is true that this is the only thing which he has, and that a man cannot lose a thing if he has it not.

This thing, what is it in itself, in its own constitution? What is its substance and material?

Let the god that is within you be the champion of the being you are.

HE WHO acts unjustly acts impiously. For since the universal nature has made rational animals for the sake of one another to help one another according to their deserts, but in no way to injure one another, he who transgresses her will, is clearly guilty of impiety towards the highest divinity.
