If I were you I'd 1) find a source of income through a business or a job. 2) sit on my money and pretend it didn't exist while I research various different ways I'd like to invest it. 3) Decide on a course of action and commit 10% and no more to whatever vehicle I decided on. 4) Execute the course of action and analyze the feedback 5) Based on the feedback I'd invest more money or move on to something else.
