If you're willing to simply get by while you work on your dream, look for an opportunity to get paid to work on that dream.

Look around. There are jobs that are incredibly boring and even afford the chance to read while you're on the job. That would be a great time for research, catching up on emails, etc

Night watchmen, late night store clerk, overnight hotel front desk person. You see these roles all the time and hardly notice.

Good luck
