Measuring the gig by hourly rate is just one way.
Measure the gig with how many family dinners get replaced with fast food.
Measure the gig with how many loads of laundry you’ll have to postpone.
Measure the gig with how many times you fall into bed with a to do list a mile long.
Measure the gig with how much slack your partner will have to pick up.
Measure the gig with all the ways it impacts your life.
Do this measuring before you take the gig. Maybe you’ll still take it, but at least you’ll know exactly what you’re being paid for.
