This looks like it's a compound noun derived from the German words Ziel (meaning "goal" in English) and Schmerz (meaning "pain" in English). A raw translation could possibly be "goal-pain," though the true definition has a deeper meaning.

Yours better fit the context, but to show off my german skills: “Target-pain” is alternative translation.
> n. the dread of finally pursuing a lifelong dream, which requires you to put your true abilities out there to be tested on the open savannah, no longer protected inside the terrarium of hopes and delusions that you started up in kindergarten and kept sealed as long as you could.
God I hope I don't fuck it up. But at least I tried.
