The net balance of his decisions, his circumstances, his random events and who knows what else.

Please please stop with this "if he's rich he must be smart" argument. Please?

As long as we stop with "if he's rich it must have been luck alone". Even a lottery winner has to buy a lottery ticket.

Ballmer was a top salesman and a notorious workaholic. Of course he needed luck, but I doubt most in his position would have netted the same billions.

>The net balance of his decisions were billions of dollars.

Billions of dollars less than it could have been, not just for Microsoft, but all Windows users combined.

If he's rich he must be fortunate, have to find out if he's smart some other way.
