Itchy feet again

why oh why do i get this feeling? had my class 2 for about 4 yrs now, i got it through work driving dustcarts, i left and returned after the logistics firm i was working for went bust, been back on dustcarts for a year and got itchy feet again. i just feel more comfortable out on the open road. yes i know the pressures and waiting around for a backload etc etc but cant shake it off. dont get me wrong, good pay, its local and have a good social life and the mrs is happy . i keep trying local pallet firms as at least itll be different work and be home most of the time, suppose i just keep e-mailing them? but surly there`s got to be a balance of a good paid secure job and being happy with what you do?
