Push

No matter how great a student you are, there will be times you get stuck and need a little encouragement. Sometimes the encouragement might be a kind word or a "you can do it!" note of support. 

Other times you will be stuck that you will need a bulldozer to get you going again. Not a real, life-sized bulldozer. Just a little one to push you in the ankles. Don't worry about it. We all need that little ankle-pushing bulldozer from time to time.
