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.
Connections help us reaching destinations literally by getting from one place to another or metaphorically speaking by using behavioural paths well travelled. If we want to reach new destinations or working on realising a dream we need to let go of some of these habitual ways of thinking and form new connections.
