The wording is misleading:

[When you move through space quickly, you move through time slowly]

Why all the “you”? This makes it sound like you would personally experience slowness. Could be clarified to say it’s only according to the perception of others.

What you will experience is the apparent size of the Universe itself changing in proportion to the time dilation along your direction of acceleration. It is necessarily an observable phenomenon due to the constancy of the speed of light.
