Side project pays $100/mo, eats every evening

$100/mo at 20 evening-hours/week is $1.25/hour. The math doesn't justify the hours unless you're learning skills you couldn't elsewhere or the path to $1k/mo is clear within 90 days. Otherwise: either commit a quarter to push it to $1k+, or sunset it. Indie purgatory drains the energy you need for the next project.
