It is like everything else. For everything there is a common way. You can first read few
books or articles on this
topic. Then simply pull out what you have decided to do and go for it. Some jobs are hard and some are
easy. Some need not much Intelligence and some are demanding for high IQ.
So choose what fits you the best and go for it. That is the first step of
business and later there is just more
work to do, beating competition, making good
products, quality of your
work etc.
Think Small.
