When the low-hanging fruit is gone, what’s left?  You’re 50% done, so doing another 25% should seem easy.  It’s only half of what you’ve already done.  And, it will get you to 75% complete.

The student fills in the outline with sentences.  The traveler chooses outfits.  The weight loss-seeker goes to the grocery store.

When the low-hanging fruit is gone, and the relatively low-hanging fruit is gone, the next step is bring the project to life.  It’s sometimes the toughest step.  But, knowing that afterwards you’ll be 75% finished makes it easier.  And seeing the light at the end of the tunnel (or in this case, the fruit on top of the tree) makes it worth it.
