There is no need to take a break if you are a bounty hunter, just leap into hunting with ease and dont stress about it if you worked in vain for a particular campaign, face the fact that bounty hunting is more like playing a lottery and not a regular paying job. When you achieve this state of mind, your stress levels will lower significantly.
Strongly agree, I myself am a bounty hunter, and have never been stressed or discouraged when the bounty project that I joined didn't pay, because it is very true that joining a bounty is almost the same as in a lottery, which is sometimes profitable and sometimes unprofitable , so there's no need to break.
