How would you fix Mark and Jez if you had the chance?

If you could time travel to Series 1 and meet the dysfunctional duo, how would you help them fix their lives?

Jeremy - I'd urge Jez to completely cut off Super Hans. We all love Super Hans, but you have to admit he's no good for Jez.

Hans has fought with Jez over Toni, got with Nancy, ignores Jez’s phone calls and dismisses his ideas, even though Hans’s own ideas are terrible (just look at his bar idea). He encourages crime, puts down the idea of having a regular job, and mocks the idea of just living a normal life.

But worst of all, he enables Jez to do drugs. Jez is already extremely lazy, cannot focus on anything and his hypersexuality constantly gets him in trouble. Smoking weed every single day and occasionally doing harder drugs just makes him lazier and hornier.

Plus, I can imagine always being high allows him to daydream and fantasize about his non-existent music career.

With Hans out of the picture, it would be easier for him to get off the drugs, stop the huge delusion about being a successful musician, and he MIGHT just get a real job. With his natural charisma and confidence, he could probably succeed in the sales department and get his life together.

Mark - I'd urge Mark to take up a martial art. Mark is smart and responsible, but his main problems seem to be his crippling fear of confrontation and total lack of social skills. He also seems to be very bored of his life, as evident by the whole Jerry situation.

Taking up a martial art could help with Mark's "I hope this guy doesn't punch me, let me just hide and say nothing forever" attitude and build his confidence.

He would also finally have another hobby. Being interested in history is great, but constantly making obscure history references and having no other interests is not great, and does not help with his already poor social skills.

Becoming less scared of everything would help open him up to new experiences, stop hating his boring life and stop obsessing over finding his "soulmate" to fill the void, which as we all know, fails miserably every time.

Then finally he could do other things rather than stalking random women or watching Jez have sex with a man through the camera he installed in his bedroom.

I know both characters are deeply flawed and this probably isn't enough - Mark would probably just falsely accuse his trainer of shitting in a pool and touching him inappropriately (like he already did) and Jez would probably make an even worse friend.

How would you go about fixing their lives?
