life becomes meaningful when your interests and opportunities at hand correlate with each other. Growing up you may had different interests in different things at different periods of your life.
But at any given moment in time if you had the opportunity to pursue and grow your interest at that time you would have flourished in that field .it's pure luck that happens some of the time. but it eventually happens
The best example of this hypothesis is the success of Bill Gates, when he was in high school he had an interest in new technology and computers he got lucky enough, his school had a computer at that time (opportunity)
There were few people his age at that time who had access to computers. Pair this opportunity with his interest in computers , thus Microsoft was born
even when you get the opportunity that once you wanted you would have lost interest in that specific area, it's the timing of these opportunities and interest. if they match up it's a bingo
This hypothesis of mine aims to depict the relation between the timing of personal interest and the opportunities you are provided with . if timed correctly it can work magic .it's mostly part of luck . if you are lucky enough you will hit the jackpot
