Dear Future,
Try to work on what makes everyone happy. Happiness isn't a commodity, and it isn't something that one needs to struggle with their whole life to obtain. Everyone has a talent and a passion that they can utilize to make the world a better place. If most of the world is struggling to survive, then they are not struggling to fill in the scientific and artistic gaps that could make humanity more fruitful.
Dear Future, this plea is for you, one year, fifty years, and ten centuries down the road. Don't wait for the world to imprison you. You have the key to your golden cages, so open them and take flight so that I may witness a million or more wings soaring freely through the skies.
Be happy, be healthy, be free in what you do.
