What I know for sure: Having the best things is no substitute for having the best life. When you can let go of the desire to acquire, you know you are really on your way.
How I feel is that if I wanted anything I'd take it. That's what I've always thought all my life. But it happens that I want you, and so I just haven't room for any other desires.
If, then, there is some end of the things we do, which we desire for its own sake (everything else being desired for the sake of this), and if we do not choose everything for the sake of something else (for at that rate the process would go on to infinity, so that our desire would be empty and vain), clearly this must be the good and the chief good.
If you have a great many desires, you will gradually eliminate them one by one, until you allow certain desires to dominate and the others to die away.
