One of the problems with considering a return to permanent employment after seven years as a freelancer is the amount of holiday time you get (or rather, the lack of holiday time you get).
For the last seven year I've been taking holidays whenever I want. I estimate that I've had about six weeks off a year on average. I haven't really had to think about it. I just take the time off and the client doesn't pay me for those days.
Now I have to consider dealing with the UK standard holiday entitlement of four weeks. I've already got five weeks planned for the second half of this year, so it seems like a lot of that will need to be curtailed
 I realise, of course, that this seems like heaven to people in other parts of the world.
