work hard work smart. save hard and spend way below your means.. start saving and invest as young/soon as possible.
Invest in whatever u r best at, whether it's property, stocks, commodity..
For me, i invest in regional stocks, and at the same time work long hours. Wait for the day your investment income overtakes your salary, and you should celebrate that day..

Do you mind me asking u your age? And when did your investment portfolio return reach your salary level?

When you said you have an investment portfolio twice your salary, you mean the return is twice your salary, or the portfolio value is twice your salary? If the return is consistently twice your salary at the age of 26, you have my utmost respect!

1998.. that was a bad year for Malaysia, but it also presented great opportunity for a lot of people..

You 16month emergency fund is definitely sufficient. I wouldnt keep that much, as if the fund is sitting idle, it may impede your other investment return.
Actually if your or your spouse parents can be depended on financially, you may need a lot less emergency fund to start with.

Start investment as early as possible, and invest in things you are most familiar with, and make sure your investment has return at least 2x FD rate, otherwise 'inflation' will just eat into all your returns.
