When ambition ends, happiness begins.
野心消亡之日，正是快乐破茧之时。
No ambition, no annoyance.
No ambition, no achievement.
Be sure you put your feet in the right place, then stand firm.
让自己站在正确的位置，然后站稳。
Honestly speaking, it is very difficult to find the right place to stand, let alone to stand firm.
Some people say when you drive hard toward one direction, you may miss other opportunities and paths, and if the direction is not so suitable for you, it will also hurt your confidence.
