Consider your deepest and most secret yearnings as if they were merely facts, so you can see ho insubstantial and hysterical they are. There is no shame in pursuing worldly success: It’s normal. Your trouble lies not in the pursuit itself, but how you pursue it. You allow your frenzied, misguided desires and fears to color your judgment. So you over evaluate the intrinsic worth of your pursuits. You bank on your pursuits to give you happiness, thus confusing means with ends.
Understand that while the pursuit of such indifferent objectives is natural, neither failure nor success in attaining them has the slightest bearing on your happiness.
