For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears;
And they shall turn away their ears from the truth, and shall be turned unto fables.

I have seen everything that is done under the sun, and behold, all is vanity and a striving after wind.

I have considered the basic desire to live a great life and how it is often secured behind a difficult choice. Those that fail to make the required sacrifice still want to have a life of meaning, though, so now they are left to seek it by less genuine means.
And to this wanting comes many, many counterfeits. Our fascination with fame and worldly glory is perhaps the greatest of these, and this obsession is little more than our misplaced desire for true greatness. We do not see our way to spiritual significance, so we redirect our attention to worldly significance instead.
Of course few that seek fame do gain it, and those that do will find it a valueless currency. Having obtained it there is nothing more for the world to offer, your progression has reached its ultimate. And then, as occurs with all things world-based things, that fame will fade, decay, and ultimately die. Some fame may last longer than others, but all of it is fundamentally transient and will eventually evaporate.
