Having two jobs suits me
1) The office job - I enjoy it, every shift is a different challenge, you come in, sit down and react to whats thrown at you, complaints, incompetant telephonists, stupid drivers, sorting out problem jobs, making sure long distance jobs go out on time, disciplining drivers. There's a lot of judgement calls and you never know what each shift has in store for you, its not one of those jons where you can have a fixed idea in your head of what you're going to do that day, that would be impossible. It keeps you fresh and provides a different challenge every time
2) The taxi driving - I do enjoy this most of the time but the incentive is purely money but thats what I enjoy about it, I want money I get in my car and earn it, I don't need money, I don't bother. But because I'm good at it, I can earn good money in a relatively short space of time.
But having said all that, If I came into significant money, I'd still give it up like a shot so I went for 7-8
