You should Give Up.
"Never give up" is the most overestimated (& misunderstood) motto out there.
There are times when giving up is the BEST thing one can do, as long as it's conceived as a form of "change," as opposed to "weakness."
But despite modern-day society praising "workaholics," winners aren't those that stick at something for the longest.
Winners recognize when it's time to stick, and when it's time to quit: they know that quitting is a necessary part of the journey, to make room for more promising paths.
Giving up ≠ Weakness
Giving up = Change
From "the dip," by Seth Godin. Highly recommend!
