Looking at the state of the world, it is easy to be pessimistic on many fronts. There are wars in the Middle East, Ukraine and elsewhere and we seem to be making no real progress on climate change.
However, there are very many fronts where progress really is being made. As mentioned earlier in the week, we can expect a big breakthrough in batteries and electric cars. Many of the world's killer diseases are being eradicated and there are far few children dying than was the case even just a few years ago.
Overall, each and every one of us has to make the world better. If we each make small steps then change for the better does occur.
