When you don’t have a job it can be tough to spend money. But any successful business person will tell you, you have to spend money to make money. So, ask a professional contact out to coffee and offer to pay. Buy a beer for someone in your field and ask them questions about how to advance your career. You could even ask them if they’d be willing to introduce you to a colleague of theirs.
The toughest decisions are made when money is tight. Ask Kellogg. They chose to spend money during the Great Depression and ending up besting C.W. Post during and after that time.
I’m not at all suggesting you should be reckless with your money, but if you are smart and faithful, you’ll be successful in the end.
