I think its an easy choice since everyone here is saying pretty much the same thing. Its short term pain for long term gain. Boxes are easy to fly and you can do things operationally in cargo that you can't do with pax as in no seat belt sign, cockpit entry security etc. I have a good paying stable job right now and yet I still plan to go brown, if and when I get out of the pool. So since you're asking go brown , its sweet just like chocolate.
Think of it this way. The good thing about cargo is there are no flight attendents, the bad thing about cargo is there are no flight attendents. Depends on how ya see it. I like the good thing and I like chocolate. Especially for the sugar/caffine buzz to lock in for the finall approach mode after being awake all night or all day depending on what time zone .
See ya in ANC.
