The road to success is hardly never straight. Sometimes there is resistance in the way and sometimes we resist to do what is needed to get ahead. Sometimes we take the challenges but don't move even a millimetre forward. Just look at Brexit - it appears to be a never ending story. Many steps have been taken yet there hasn't been much progress to date. I am sure that there are many other similar examples in your immediate environment. Often the effort we have put in leads to frustration instead of success.
