One other thought, dear students and colleagues:

Around 500 B.C., the Chinese philosopher Lao Zi (Lao Tzu, if you use Wade-Giles Romanization rather than Pinyin) wrote:

千里之行始于足下
（qian li zhi xing shiyu zu xia)
="A journey of a thousand miles begins with a single step".

The words translated "single step" might also be translated as "putting your foot down".
So, let's put our feet down and go forward, determined to study and accomplish great things.
