The first one, that is to say, one is personality and the other is choice.
Second, the expression means persistence and independence. Think independently, not be changed by others, and stick to the ultimate goal.
Third, means of expression, people's hearts. Take Fo Yin and Su Dongpo as examples. Fo Yin thinks Su Dongpo is a Buddha, and Su Dongpo thinks Fo Yin is shit. Su Dongpo thought he had won, and Su Xiaomei told him that Fo Yin had a Buddha in his heart and everyone was a Buddha. Su Dongpo's heart is shit, so everyone else is shit. So this expression means that the world you see is a concrete impression of your heart. There is beauty in the heart, and nature is a beautiful world. There are evil spirits in my heart, and everyone else is evil spirits.
See what you want to express, and then you can decide which is better.
