I like this part because most investors only think about the positive aspects of their investment without thinking about if thing happens the other way round. As an investor, there is need to calculate your the risks involved in your investment and bear in mind that there will surely come bad times when it look as if you have made the wrong investment decision but those challenges are what makes an investor become stronger to still continue without feeling the impact of how the market turned out. Having the feeling that you can lose all your investment will give you the idea to not invest all your money but with just what you can afford to let go without feeling bad about it.
