I watched 10 minutes and just got annoyed by McCarthy's smug attitude. He really has the typical unfounded arrogance of the modern teen. He reminds me so much of the kids in college when I returned in 2006 and was 6-7 older than all of them. So many strong opinions, so little ability to view other people's perspectives.
Mind you, I had many strong 'opinions' as a teenager as well. It took me a while to realise that I didn't know much about anything, perhaps this fella will mature as he gains more experience and be less inclined to shoot down everything he doesn't agree with. At a guess, I'd say many of McCarthy's 'followers' are in the 16-25 bracket.
No excuses, just results.
Getting it done one session at a time.
