Investor harus mulai dengan pandangan skeptis. Mereka harus menjadi investor intelektual daripada investor emosional. Mereka harus berhati-hati, dan mereka harus skeptis. Asli: Investors should start with a view of skepticism. They should become intellectual investors rather than emotional investors. They should be careful, and they should be skeptical.
