If tank man can stand up to the overwhelming power of the Chinese authoritarian regime then it gives me hope that I can overcome the things that prevent me from realizing less suffering.

It tells me that we are much stronger than we realize and is a powerfully motivating reminder that yes, indeed I will realize liberation because the potential is there and I need that reminder to keep me motivated.
