Do people who suck know that they suck?

Hmm i kinda set myself up for that one. You won this round!

But for real like i have a guy i work with who is a really nice guy but man he fails at life so hard. 30 years old 4 ex-wives, 6 kids, tons of debt including delinquent debt, 20% car loan, etc etc etc oh and lives in a trailer and aspires to buy a smoky and the bantdit f-bod. Anyhow i have spent countless hours trying to help this guy plan budgets, consolidate debt, go back to school and no matter what he seems to always find a way to screw things up. He is aware of how bad he sucks and is trying to fix it but i do not se him not sucking for quite some time.
