Difficulties break some men but make others. No axe is sharp enough to cut the soul of a sinner who keeps on trying, one armed with the hope that he will rise even in the end.

Persistence is very important. You should not give up unless you are forced to give up.

Wherever you are in your journey, I hope you, too, will keep encountering challenges. It is a blessing to be able to survive them, to be able to keep putting one foot in front of the other-to be in a position to make the climb up life's mountain, knowing that the summit still lies ahead. And every experience is a valuable teacher.
