I'm a paranoid sob and hopefully my paranoia can help you. 1. Write down a plan of what you'll be woerking on. 2. Contact companies that work in this field and ask them if they would give you a job if you were an expert in the fields your going to work in. 3. Can u work alone? It gets very lonely. Figure out all the mechanics of how your going to work on your own. You'll be surprised that setting this up to be fun can be a lot of work. 4. Do it!!! at some point you have to make a leap of faith. Just be sure you've covered the worst case scenaios (ie have some back up plan) and then jump!

As long as your skills are valuable to someone you will be able to get a job.
