Guy I started out working for did.
He ran 5 people, 3 vans, quite a big unit with office etc...
Had a heart attack.
Realised that money can't buy you live, health or friends and sold most if it off.
Now just runs his own van-bet he still turns £40k, buddies up with a guy that doesn't speak English occasionally and from what I can see is much happier.
I actually applaud people who realise that there are more important things than money. Just getting there myself.
