The practical reality of managing cars in the family - I do 36-month leases. I think they're horrible investments. And you want to give them back after their warranty is over.

Working 24 hours a day isn't enough anymore. You have to be willing to sacrifice everything to be successful, including your personal life, your family life, maybe more. If people think it's any less, they're wrong, and they will fail.

You may lose your wife, you may lose your dog, your mother may hate you. None of those things matter. What matters is that you achieve success and become free. Then you can do whatever you like.
