>> Success is simply a matter of luck. Ask any failure.
On a serious note the opportunity that leads to success can be a matter of right place/right time.
My father succeeded as a partner in a business importing dyes and chemicals for the textile industry. The opportunity arose because he was employed by another business at exactly the time it decided to be UK agent for one rather than two European manufacturers. He also had immediate colleagues of like mind and who, as a team, had the backing, contacts and skills to make it work.
