Who can decide whether I will stay or not and decide the universe in my heart depends on my waving hands and ideals. I thought about success, I thought about failure, but I never thought about giving up. Being content with the status quo is not my character, and mediocrity is not my goal.
If you have been injured n times, you must work hard with the power of n. Fate is like a palm print. Although twists and turns, but always in their own hands.
