Let's make this a better world... why the world won't change...

Dear readers,
everybody would like to change the world. All of us would like to live in a better society than the one we live in, all people would love to have peace on earth, food and water for everyone and so on. Why is that impossible? How a great bluesman once used to sing, "everybody wants to go to heaven but nobody wants to die". In other words, everybody wants to change the world, but nobody wants to change. In fact, the most common human fault is selfishness.

I think the world will change only after millions of people forget their own needs, wishes and problems to inform and help others. Only changing ourselves will enable us to change the world, and anyway that would take hundreds of years.
However, there are many people in the world who already do this: they forget their own needs to think about other people. I believe most of them do it on a fulltime basis, but there are also many who do it during their free time. The most important principle is, as Michael Jackson said, "...if you wanna make the world a better place, take a look at yourself and then make the change...".
I also had joined a group of people who fight for a better world, but I left it when I realized that most of it was just talk and frustration. When it was time to come together and speak about what could be done and how, share ideas and information, organize events and actions, the usual three or four actually showed up and all turned to dust.
Why is all this so difficult, if not impossible? Because in our society now we have too much for ourselves, too many possibilities, too many rights, too many freedoms, basically, too much of everything. We don't appreciate life anymore, we always want more, we want to have the best performance with the least effort. Of course, many people are not like that, but most of the people who have the power to change things are so, especially politicians and business people. After all, even the ancient Greeks told us that politics is corruption, but as Sting said, "history will teach us nothing".
What should we change in the world anyway? Basically, everything. First of all, introduce renewable energy sources as the only options for the future and stop destroying our environment but even the fear of a climate catastrophe does not stop politicians and tycoons to finance and build monsters like coal power stations and incinerators. Secondly, design and make products that have a very long life cycle and buy and consume local products. Then, reorganize the school system, social services, judicial system and most important, think more about the future. Many other things should be changed but I think nothing will ever change, at least not in the next few centuries. Obama? Maybe a starting point, maybe not.
However, hope is the last to die and of course, the show must go on.
