我若不勇敢谁替我坚强我若不坚强谁替我勇敢
[wŏ ruò bù yŏng găn shéi tì wŏ jiān qiáng wŏ ruò bù jiān qiáng shéi tì wŏ yŏng găn]
This means if I don’t summon the courage, who will become strong for me; and conversely, if I don’t grow strong, then who will find the bravery for me? It's a statement showing interconnection between courage and strength, suggesting self-motivation.
