I find that you really can't make money without spending 1) a lot of time and efforts or 2) managements and money
With the 1), there is exception, that is if you have tons of credibility, skills, and knowledge on specific trade that could make you a lot of money w/ simple consulting and stuff.
with 2) use money to buy talents and time from merchants and employees to work for you
3) Start from scratch and use a lot of sweats and labors to build something up. But the hidden cost is TIME. a lot of time.
