I feel inferior when I see someone else driving a Mercedes-Benz BMW. People are all the same, why can't I do it? People are the same. Why can't we change our efforts?

What about going your own way? There are many such things in life. Although you have paid and shed sweat, you may live a more fulfilling life than those local tyrants. It is not terrible to need difficulties in life. The terrible thing is that after encountering difficulties, I can't find the direction and finally lose myself!
