Change is part of the work we do. We need to adapt to changes. If we cannot change we must quit. We all go through tough situations where things seem not to work regardless of our invested efforts. We then wonder if the goal is worth all the trouble. Where we think it is indeed worth it, we ask ourselves whether we will succeed amid all obstacles. It is human nature to worry when things do not go as planned and, it is good to do evaluations and make adjustments where strategies are not yielding the expected results.
