Answer by Ejaz Altaf:
What has worked for me are the following strategies;
1. Start saving from day one of your career. Pay yourself first.
2. Start a side business while keeping your full-time job.
3. Work hard for many years. I mean 6-7 days a week and take long weekends for vacations.
4. Invest your savings wisely yet conservatively. Don't chase returns.
These are sure ways to breaking into the millionare zone. Of course one can also work at a series of start-ups or invent either a product or service etc.
My milage has been all of the above including working for a series of start-ups (they have made my intellect much richer today for my business).
