I recently discovered this quote from President Monson.
I have spoken over the years with many individuals who have told me, “I have so many problems, such real concerns. I’m overwhelmed with the challenges of life. What can I do?” I have offered to them, and I now offer to you, this specific suggestion: seek heavenly guidance one day at a time. Life by the yard is hard; by the inch it’s a cinch. Each of us can be true for just one day—and then one more and then one more after that—until we’ve lived a lifetime guided by the Spirit, a lifetime close to the Lord, a lifetime of good deeds and righteousness. The Savior promised, “Look unto me, and endure to the end, and ye shall live; for unto him that endureth to the end will I give eternal life.”
