Have a break... it might do you some good
Is a change as good as a rest? Do holidays recharge batteries and help you think afresh on your return to work? As someone who likes routine, and then gets to feel trapped by routine, these questions often exercise my mind in idle moments.
In the last while I have met people at different stages in life who were all contemplating major changes, either in what they did or where they lived. I know these feelings well.
They can become quite unsettling if you don't do something about it.
