We're in the business of happiness.
The worst job you've ever had at least helped with the basics of your life. You got a paycheck (occasionally) and you were able to pay the rent, buy food, and sleep knowing you probably had a job tomorrow. Chances are they even provided you with a toilet and a water facet (maybe even coffee) at work. That's ok. You were working for them and yet conceived where you were headed.
Your second worst job almost felt like a career. Finally you were you felt more more financially secure. The work took real skill and was doing something useful for other people. You bought some toys.
