Relevance is subjective, and at some point in time we are all relevant to someone in a certain situation. Some that have great achievements on this planet, such as great doctors or inventors,might be more relevant than a shepard, but ultimately,considering that the whole Universe is some big oneness we are all relevant. It's a pitty that money have become too relevant, apparently. It's usually poor countries where the cult of money is deeply rooted in the majority of the population. I'm coming from Eastern Europe and in here almost anything is about money. Considering the resources the planet has and the evolution of technology there shouldn't be any poor country in the worl.
Your words are so deep and I could relate very well with them. The truth is we are all relevant in all our endeavors, just that one is higher than the others in terms of contribution and input.
