It doesn't just happen on the mission either. There are many things in life that require hard work all the way through. Did you make new years resolutions? Does the word Senior-itis sound familiar? How much of your high school Spanish do you remember? Can you still play those songs you learned on the piano?
There are many opportunities wasted when we don't endure to the end. Here is a poem I recently memorized to help me finish strong.
Stick to your task ’til it sticks to you;
Beginners are many, but enders are few.
Honor, power, place and praise
Will always come to the one who stays.
Stick to your task ’til it sticks to you;
Bend at it, sweat at it, smile at it, too;
For out of the bend and the sweat and the smile
Will come life’s victories after a while.
