Dan Pena
the best coach in this field
has the savest method to become rich fast - no common "get rich quick scheme"
created billions of dollars in wealth if you count the success of his mentees
created on his own half a billion of net worth, before he started coaching
a 40% success probability, which is much in this field
it is based on borrowing money
currently, the interest rate is on its lowest point ever in history
however, it probably will explode in the next years, so would not borrow too much money
his seminars costs between 20k and 30k USD
you live in a castle for 7 days
only 30 people are taken
this year it is probably his last seminar
you can download his book for free and watch videos, interviews etc.
The Four Hour Work Week
a classic, which contains all the information you need for an internet business
still applies, however you have to do your own research
Should be enough and you can find the rest on the internet. And don't waste too much time on the technical stuff. Create prototypes at the beginning, if it works you can extend.
I would recommend starting with freelancing, because it is easier most of the time and you get a glimpse how it is to have an own business.
