Because sometimes, it is you. In fact, most of the time, it’s in your best interest to stick it out, see it through, and turn your obstacle into an opportunity.
But then there are those times when it’s not you, it’s the opportunity. There may come a time when you have to call it what it is and find a different way because the obstacle isn’t worth your effort.
Again, this is usually the exception.
So how do you tell whether it’s you or the opportunity? Look for patterns. Are you constantly unsatisfied? Have you felt undervalued at other places? Were you not a culture fit before? It’s probably you. Do they have turnover issues? Are they constantly overpromising and under-delivering? Are they ‘hiring for culture fit’ as a means to discriminate? It’s likely the opportunity.
