You live in a fantasy land if you think happiness is affording the car you want. True happiness does not come from obtaining worldly possessions. They only give you temporary false feelings of happiness. No matter how much you love that new car, sooner or later that love goes by the wayside because that car cannot return those feelings of love for you ... unless it's a Transformer, of course. And when it all comes down to it, you'll fall in love with another new car as time passes.
Another thing, you simplify his new life too much. You make it seem like he's only getting paid to go play 82 games a season from October thru April, 48 minutes per game. It's far more complicated than that.
Finally, you know nothing about Beasley the person. All you know about Beasley is that he plays basketball at a higher competitive level than you likely ever will and yet you assume that because he gets paid millions of dollars to play apparently only 48 minutes on 82 nights of action that all mental and physical strains he's ever had in his life miraculously disappear. The human psyche does not work in that fashion.
