"You can't produce a baby in one month by getting nine women pregnant."
-- Warren Buffett
Concentrate on a goal you have set so that you can work it out to success. Collecting goals will wobble your path because you have to fulfill different task to achieve a slice of another goal.
You cannot put up businesses and watch them prosper because you will not have the time to take care of them all. Aside form the waste of money and time, its a waste of intelligence.
Better to concentrate on one and when it is self-standing then you can set another goal or put up another business.
