Work on yourself for a prosperous life.
Back in the age of King Arthur a tyrant called Vortigern seized the British throne, he made a series of mistakes including allowing the Saxons into Romano-Britain, a people who would never leave, starting a 400-year war for control of Britain. Vortigern fled to Mount Snowdon in Wales where he attempted to build a great castle. Every time the castle was built it collapsed, Vortigern turned to a young boy called Merlin for help. Undertaking a role of pest control officer Merlin discovered Vortigern had a problem worse than termites, two fighting dragons. I am unsure what happened to the dragons, but Merlin made a lot of prophecies and resolved the problem for Vortigern. Vortigern built his castle, and then died in it when his enemies burnt it to the ground. The problem with Vortigern is he tried to build a life for himself on weak foundations and unresolved issues, his troubles and fiery end was a predictable consequence.
I have attended a few church marriages of friends, and a story that is told in some of those churches stuck in my mind about those who build their house upon sand, facing wind and flood the house falls, the house built on rocks survives. I have seen over the years too many marriages of those around me collapse into ruin. Life is unforgiving, it raises trials and tribulations that will test your metal, better to work on self, to establish strong foundations before building castles.
