Zack and his wife Adrienne try desperately to be adults by setting small goals for themselves, doing research, and checking in monthly to see how they've done. A lot of the times the answer is 'failure', but they will keep trying!
Through trying and failing, they hope to give other people struggling to just operate in this difficult capitalist system both hope that they can improve as well as an example that its okay to fail - as long as you do your best.
Also they tell a lot of dick jokes and stories about Zack hurting himself in comical ways, because that's just how these things go.
