My wisdom for future generations

It is the year 2088. I am 100 years old and I decide to pass on my elder's wisdom.

"Much has changed in life. Because of the clime change it is now possible to practice agriculture in the areas like in the north of the Scandinavia, Russia and Siberia. In the countries like central Africa it is impossible to live because of the heat and water deficiency. There was a great mass migration in the year 2050.
Novel Communication technologies have made possible that everyone in the world has access to internet. The wh*** social process and work is done from the internet. Many jobs got lost like teacher or professor because nowadays you can learn via internet comfortable at home. Virtual communities have crystallized out. The political importance of countries like India, Brazil, and China has grown. The Western culture has lost its strong position in the world.
But although there were many changes in the world, we must always remember that we, humans, are a part of nature. Our world, the nature, people are all unique. We are responsible for the future of our world so we have to ensure that this future is preserved for our children and next generations. We have to protect nature and to appreciate its uniqueness.

But one thing I have to say my children. If you get sad or think there is no way to solve a certain problem, so then looking up at the stars in the sky. You will see the beauty and the magic of the stars. Because these stars will be always seen in the sky during our live goes past someday and then you will notice that there is no reason to be sad or the problem isn't so big like you have thought at first, because our life, compared with the lifetime of the stars, is too short for being sad or making your life more difficult than it need be.
