I found this old prayer online in this free ebook: The Ursuline Manual. It is a very beautiful prayer and one we should take to heart.
O my God, make me prudent in my undertakings, courageous in danger, patient in afflictions, and humble in prosperity.
Grant that I may ever be attentive at my prayers, temperate at my meals, diligent in my employments, and constant in my resolutions.
Let my conscience be ever upright and pure, my exterior modest, my conversation edifying, and my comportment regular.
Assist me, that I may continually labour to overcome nature, to correspond with thy grace, to keep thy commandments, and to work out my salvation.
Discover to me, O my God, the nothingness of this world, the greatness of heaven, the shortness of time, and the length of eternity.
Grant that I may prepare for death, that I may fear thy judgements, that I may escape hell, and in the end, obtain heaven, through Jesus Christ Our Lord who liveth and reigneth with the Father and the Holy Ghost, one God, world without end.
