Spending some time on a good resume / CV / portfolio would probably be a good investment with positive ROI.
Is there a nonprofit that you could volunteer with to increase your hireability during the other 158 hours of the week?
Or an online course with a credential that may or may not have positive ROI as a resume item?
Is there a code school in your city with a "you don't pay unless you land a full time job with a living wage and benefits" guarantee?
What is your strategy for business and career networking?
