The answer to the question about what could help the world to be a better place can be long and complex. And, above all, in the current times, we need it to be simple and brief so that we do not lose sight of which are the main objectives, so that these will not be diluted with the rest and lose relevance. Nor can it be simplified so much that, in the end, expressed in an exhaustive manner, then nothing is said.
Consequently, I will try to specify that I think it could help more to make the world a better place. So, after reflecting on it, I have come to consider these that there is only one key factor in helping to achieve a better world.
