For me reintegration was unexpectedly hard. I took off cruising the first time in 2001. The plan was to
cruise part of the year and
work in the business the remainder (very intense environment).
I never gave reintegration a thought, but found it surprisingly hard on my return.
Tried to get back up to speed for a couple of years and just never got there.
My solution was to fire myself for poor performance

and take off cruising again with the intent of never returning...wow, its now 2017!
