I had a few months between jacking in my London job and starting the job I had lined up in Glasgow so I went to South America. I don’t have the personality to be able to just chuck in a job for a break (regardless of cash in bank) without having a very clear plan of what job I would be doing next and when- I know I simply wouldn’t be able to enjoy the time off and so I’ve never tried it.
I had a very enjoyable few months off to have a baby 9although again, I was able to enjoy that time because I knew it was finite and I have my lovely safety net of fulfilling job to return to.)
I think if you are braver than me (and perhaps if you don’t have ties/ overheads to worry about) then it could be a very liberating thing to do. Just don’t fritter it away because presumably at some point in the future you may want a ‘career’ again and you may have to explain this ‘time out’ to people who are not as open minded as you.
