What Warren Buffett’s life has taught us, more than anything else, is that a life of passion is also a life of obsession, and that the two walk hand-in-hand. When you are living a life of passion and obsession, there are no limits. There are no time clocks or time off, no vacations, no bosses breathing down your neck to perform, because with obsession, there is no boss, there is only you. There is only your obsession and wanting to work on it day after day as a means of perfecting it and making it fully your own.
