Our worldly successes cannot be guaranteed, but our ability to achieve spiritual success is entirely up to us, thanks to the grace of God. The best advice I know is to give is to give those worldly things your best but never your all - reserve the ultimate hope for the only one who can grant it.
I am responsible. Although I may not be able to prevent the worst from happening, I am responsible for my attitude toward the inevitable misfortunes that darken life. Bad things do happen; how I respond to them defines my character and the quality of my life. I can choose to sit in perpetual sadness, immobilized by the gravity of my loss, or I can choose to rise from the pain and treasure the most precious gift I have ? life itself.
