Neither of you do anything halfheartedly and you both have strong, powerful convictions.

你需要以正确的方式设置目标-让自己成功，而不是三心两意的一个模糊梦想。

You need to set goals in the right way - setting yourself up for success, rather than half-heartedly aiming for a vague dream.

在最初的时候，人们通常以为人的情绪是由“心”释放的，所以有了“伤心”“痛心”“开心”“三心两意”“心猿意马”....

People believed for a long time that the heart was the center of a person's emotions.
