I was employed as an electrical hardware engineer for a computer peripherals company until November 2014. The job market for electrical engineers in San Diego is currently in an awful state.
While I was employed, I managed to buy a vacation home which I converted to a rental property after I became unemployed. I also was able to build a large nest egg of investments and cash. I am using these to live off of at the moment.
I am Financially Independent to the point where I can pay for basic living costs, but not for fancy stuff like eating out or vacations.
When I became unemployed, I updated my home engineering lab with a new test equipment by selling items on Ebay which I no longer needed. I currently spend a lot of my time developing open source hardware,firmware, and software and upload my projects to Github.
If the job market in San Diego improves, I would consider going back to work, but it would have to be on my terms. I have enjoyed not having to commute to work every weekday. Any new job would have allow 80 to 100% telecommuting.
Financial independence can be achieved, but it requires sacrifice and dedication. For details on how to do this I recommend visiting the Mr. Money Mustache blog: http://www.mrmoneymustache.com for ideas and support.
