go on a long backpacking trip

I’ve had this strong feeling lately of wanting to get out and do something for days at a time. That’s one reason I quit/change jobs all the time. I can’t just get up and take off when I need to. I’m sort of hesitant about joining UPS- I wonder if I should go on this hike and then try applying again. I don’t want to screw up the chance to get in right off, though. I’ve already passed the job interview, background check etc and basically have the job so long as I confirm and fill out the paperwork.
