Searching for online income

It has been my goal for a long time to find a way to make money online.  This blog has been going strong now for a number of months.  I use Amazon adverting and an affiliate link.  I enter every contest that I can.  I have offered various services at Craig's List.  So far, no income and no bites.  I am not sure what will open that door or start the adventure.  There seems to be some hurdle that I can't seem to overcome.  My guess is that I do not have anything unique enough or exciting enough for people to buy.  I am an entrepreneur wannabe.  Business owners are people I look up too.  I would love to have my own company because I would like to have ownership and be in a decision making role.  It would be fun to build something with my name on it.  Instead of the usual punch-in and punch-out role of an employee, I would rather come to work and work on something important.  At the end of my time working on the company, I would have an asset to sell.  As an employee, on your last day, they give you your last paycheck and forget about you.  There is nothing to sell.  I have been through that routine so many times and it is disheartening.  My acres of diamonds are somewhere.  I just need to see them.
