He works stupendously hard. Growing up my dad was always working, and it factored heavily into my decision to not pursue a career of long hours, it&#x27;s a trade-off I wasn&#x27;t willing to make. As a consequence, I won&#x27;t have the financial resources he has. The amount of dedication that it takes to run businesses like tesla and spacex well is intimidating. To quote princess bride, it leaves no room for dilly-dallying.<p>Another take-away I get from musk&#x27;s achievements is that the best software businesses are about applied software. Paypal is software applied to finance, tesla is software applied to cars, spacex is software applied to rockets. Combine great software with great hardware, and you get companies like apple, tesla, spacex, companies that change the world.
